feat(connections): remember database passwords in the OS secret store - #777
A named PostGIS, MySQL/MariaDB or SQL Server connection can keep its password in the operating
system's password store (macOS Keychain, Windows Credential Manager, the Secret Service), behind
an unchecked Remember on this computer opt-in in the new, edit and login forms. Nothing is
saved unless that is checked, Test never persists anything, and the browser and the command
line stay session-only.
Lifetime is bound to the definition, not the address. The store holds an envelope of the
connection's kind, cleaned address and password under connection/<id>, and it is only used when
it still matches the saved definition. Ids are sequential (c1, c2), so a reused id, a stale
account from reset preferences or an interrupted address edit can never attach an old password to
a new server. Renaming or regrouping keeps the password; changing the address or username, or
removing the connection, deletes the old account first and leaves the definition unchanged if
that fails. Duplicating copies neither the stored password nor the session login. A corrupt or
mismatched envelope clears the remembered marker and sends nothing.
Projects stay address-only. Opening one resolves each database by its exact driver address:
one remembered match reconnects automatically, several queue a chooser with no default, and none
keeps today's password-free behaviour. Only the wrapper, outer whitespace and password are set
aside — URI and libpq forms, reordered parameters, host aliases and different usernames are not
treated as the same server. Precedence is explicit session input or selection > saved password >
existing ambient fallbacks, and opening a project still never newly authorizes PGPASSWORD, MYSQL_PWD, SQLCMDPASSWORD, ~/.pgpass or Windows integrated sign-in. A password the server
refuses is suppressed for the rest of the session without touching the stored value; replacing it
takes a new login with Remember checked. Ambient fallbacks and the drivers' existing ask: false
protection are untouched.
Command surface (the part worth a maintainer's eye, since it changes an existing command):
connection.login gains an optional "remember" boolean (default false, rejected for
non-database kinds) and now accepts {"id"} with no password, which explicitly selects that
connection's existing session or remembered password. A remember:true login also returns "passwordSaved", and "warning" when a store couldn't keep a usable password.
connection.forgetPassword {"id"} is new: it deletes the stored value and clears the marker,
leaving an explicitly entered session password and already-open layers alone. It never selects an
inactive connection or replaces another connection's or an unowned address's active password.
connection.list reports "remembered", per-id "loggedIn" (no longer attributing an address's
cache entry to every connection at that address; includes an already-loaded remembered password,
without reading the store during listing, and does not claim authentication succeeded) and a
secret-free "loginRequests" array
(reason, database label, candidate ids, affected-layer count) that scripts and the assistant can
act on with connection.login {"id"}.
.rgis is unchanged: no format change, no connection ids in the project. No new dependency, so deny.toml and the third-party notices are unaffected.
The other half of the change is containment: the driver's active-password slot now records which
saved id activated it, so switching to c2 cannot inherit c1's password and clearing for a
project load preserves explicitly typed ones; connection.forgetPassword is reserved to the user
(plugins cannot run it, the assistant asks each time); and driver errors are redacted of the
active password at connect, query and reconnect boundaries while keeping DataError::Login, so a
server that echoes the password cannot put it in a notice, a layer's error or a command result.
Testing
cargo xtask ci (fmt, clippy -D warnings, the whole workspace suite, layers) and pre-commit run --all-files pass on the rebased tree.
On b5ab090, CI also
passed Rust tests and layering on Linux, macOS and Windows, the browser build, lint, licences
and notices. The Python package run
passed too, including Windows Python 3.14. Release-app builds were skipped (no ci:full label).
These CI results do not claim live Windows/Linux OS-store verification.
Plus:
Real password packets.cargo test -p rustgis-engine remembered_database_ (20 tests) drives
a loopback PostgreSQL handshake and asserts the bytes the driver actually sends: a unique exact
saved match sends the saved password and only once per source group; another host, port, user,
URI form or reordered address sends nothing; an explicitly typed address password wins; a saved
password wins over an ambient PGPASSWORD (checked in a child process, since the variable is
process-global); two remembered same-address ids queue choose and send neither until connection.login {"id":c2} sends only c2's.
Refusal and recovery. A 28P01 refusal marks the layer login-required, queues a password
request, keeps the stored value and asks no other saved password; an unchecked replacement does
not overwrite it, a checked one does. A transport failure or a missing table is not reported as
a wrong password. The review regressions additionally exercise inactive-connection Forget,
active versus unowned driver-slot ownership, saved-only activation cleanup, and per-id status.
A named Test that receives a positive authentication refusal restores the previous session
password, selection and exact driver-slot owner/value (or removes an attempt with no prior
credential). Successful authentication followed by a listing error keeps the new session
password. Neither Test path writes the store. Both subprocess helpers require exactly one
passing, non-ignored child test, not merely a successful exit.
Scoped resolution. A project with one layer waiting on a database whose saved password
authenticates but whose catalogue read fails stays re-resolvable: the loopback server sees the
connect from the project open, sees nothing after connection.new for a different address, and
sees the connect again after connection.new/connection.remove at that same address. Reverting
the scoped resolver to a full resolve fails the test with an unexpected password packet.
Login state. A refused password typed for connection.login is sent but is not kept as that
id's session credential, so it is not reported as available and cannot be reused by a later
resolve or Browse; and a login that turns out to have no password of its own fails without
deactivating the password another connection is using for that address; and a refused attempt is
made once per database rather than once per waiting layer, typed or saved.
Confirmed typed-login refusals restore the previous driver password and owner, selection and
activation; with no previous slot, the attempted password is removed. Packet regressions
verify the next driver read for same-ID, other-ID and unowned address credentials, plus the
empty-slot case. A standalone native smoke exercised all four cases.
Separately, refusal of a reused cached-session password evicts that session value, its driver
entry and activation. An equivalent saved value is also suppressed for that session; a
different saved value is not marked refused. This includes invalidated saved-cache cases and
leaves the OS-store entry unchanged. Packet regressions verify
eviction and no resend on a password-free retry through login, Test, Browse and project open;
authenticated listing failures retain the credential. A native smoke exercised both outcomes
through those four entry points.
UI.cargo test -p rustgis-ui-egui --test smoke remembered_database_ (5 tests) clicks the
real checkbox and buttons with an injected MemorySecrets: unchecked by default and after
reopening, Test does not persist, Save does, Forget removes the stored value but not the
connection, chooser Cancel leaves the layers unavailable and selection works, a refusal opens an
empty unchecked form, a failing store keeps the session login and shows a notice, and a project
scope check. A leak check walks preferences, Project::saved_text, the recording, History, sources.list/connection.list, notices and the runtime state's Debug for a sentinel.
Assistant and plugins.cargo test -p rustgis-assistant remembered_database_ proves a
direct and scripted Forget needs fresh approval and executes nothing before it, and the
reserved-command list covers it.
The real OS store.cargo test -p rustgis keychain_round_trip -- --ignored against its
dedicated test account.
A real server. Against a disposable PostgreSQL 18 cluster with scram-sha-256 auth and log_connections=on: the saved password produced an authenticated session (the server log
records connection authenticated: identity="live_saved" method=scram-sha-256, and the layer
then fails with "the database has no PostGIS"), while the wrong saved password was refused with password authentication failed for user "live_wrong", no authenticated session for that role,
and a fresh password request. Cluster removed afterwards.
wasm.cargo build --target wasm32-unknown-unknown -p rustgis-web (needs clang for the
Zstandard decoder, as AGENTS.md says).
Screenshots.ui_shot was used to check the translated form, the unchecked checkbox, the
layout and the unchanged S3 form, and a throwaway harness captured the remembered row, its
Forget menu and the no-default chooser.
Related issue
Closes#755. Follows the secret store from #767, whose SecretStore, Secret and MemorySecrets
this builds on without adding a dependency.
Notes for the reviewer
The change touches platform-specific code paths (the OS store, and desktop-only database
drivers), so ci:windows and ci:macos would be useful; only macOS was exercised locally.
Not exercised anywhere: a live geometry-table load through PostGIS (not installed locally — the
authenticated session above ends at the extension check), and the Windows and Linux stores.
docs/user-guide/data.md is updated for the new policy, including the paragraphs that said a
database password is only ever session-scoped.
Summary by CodeRabbit
New Features
Desktop users can opt in to saving database passwords for named connections, reuse them when reconnecting, and forget them later. Passwords remain session-only by default elsewhere.
When a project database matches multiple saved connections, users can choose which connection to use. Failed saved-password attempts prompt for credentials again.
Connection listings show saved-password status, and login prompts guide users through choosing a connection or retrying login. Waiting layers can reopen after a matching connection is selected.
Users can browse and test named database connections with saved or session credentials. Assistant-initiated password removal requires fresh approval.
Bug Fixes
Database error messages no longer expose configured passwords.
Documentation
Updated the database guide with password-saving, reconnection, and connection-selection details.
A named PostGIS, MySQL/MariaDB or SQL Server connection can keep its password
in the operating system's password store, behind an unchecked "Remember on
this computer" opt-in in the new, edit and login forms. Nothing is saved by
default, Test never persists, and the browser and CLI stay session-only.
The stored value is an envelope bound to the connection's id, kind and cleaned
address, so a reused id, an interrupted address edit or an old preference never
sends an old password. Rename and group edits keep it; an address or username
edit, a removal and Forget delete it first and leave the definition unchanged
if that fails. Projects stay address-only: opening one reconnects only a unique
exact-address remembered match, offers a chooser when several match, and never
newly authorizes ambient credentials. A refused saved password is suppressed
for the session without touching the store.
connection.forgetPassword forgets a stored password; it is reserved to the
user, so plugins cannot run it and the assistant asks each time. Driver errors
are redacted of the active password at connect, query and reconnect boundaries,
keeping DataError::Login.

A rabbit checks the saved-key store, And finds the password waiting there. It asks before it saves or clears, Then hops through layers with care. No secret trails in logs remain, The moonlit maps open again.
Comment @coderabbitai help to get the list of available commands.
Posted two inline comments and now writing the summary. I read about two-thirds of the diff and not the UI files, so the review isn't complete.
Code review
I read pr-context/diff.patch through line 2199 of roughly 2,200+ lines, and checked a few changed lines against the checkout. I did not read the remaining test files, the docs, or crates/ui-egui (connectionui.rs, panes.rs, sourcespane.rs and the remembered_database UI tests). Nothing was built or run.
The design is careful. Saved passwords go to the OS store inside a kind-and-address envelope, so a reused connection id can't pick up another server's password. Edit and remove delete the saved password before they change the connection list. Errors are redacted before they surface, with packet-level tests behind that. I found no crashes, secret leaks or layering problems in what I read.
Bugs
connection.test keeps a failed password (crates/engine/src/cmd/connections.rs:564, medium confidence). The password is stored as the connection's session password before the test runs. A failed test leaves it in place, so the connection shows loggedIn: true and a mistyped password replaces a working one. It would be safer to hold the password locally and commit it only on success.
Security
Nothing found in the parts I read. I checked the envelope matching, the redaction of Login, Format and Io errors, connection.forgetPassword being in the plugin NEVER list, and the assistant approval tests.
Performance
Nothing significant. resolve_project and groups walk all layers on each connection change, which is fine at project scale.
Quality
Redaction of very short passwords (crates/data/src/lib.rs:64, low confidence, nit). without_secret is a plain substring replace, so a one- or two-character password mangles every matching character in the error text. It is safe but unreadable.
Fragile test isolation (low confidence). remembered_database_packets.rs re-runs the test binary through current_exe() with --exact tests::remembered_database_packets::<name>. A module rename would silently break it.
Large new surface (info). connections.rs and cmd/connections.rs grew a lot. The activation, selection, rejection and request bookkeeping in DatabaseLogins is intricate, so the packet-level tests are worth keeping.
AGENTS.md
No violations seen in the production code I read (no unwrap or panic, wasm cfg gating present, the new command is registered in the plugin NEVER list).
New interface text in the UI files was not checked against tl! or i18n::fmt.
A new dependency, if any, would need cargo xtask notices; I saw no manifest changes.

I read the Rust changes in the diff and did not build or run anything. The design is careful: the stored envelope is bound to kind and address, deletes happen before the definition changes, and connection.forgetPassword is blocked for plugins and needs fresh approval in the assistant. I found no definite bugs. The concerns below are medium or low confidence, and three are posted inline.
Bugs
Medium (inline):delete_account in crates/engine/src/cmd/connections.rs asks the OS store to delete even when the connection was never remembered. A locked, denied or unavailable keychain then blocks connection.remove and an address connection.edit, even though no password was saved.
Low-medium: In redact_secret (crates/data/src/lib.rs), a very short password such as a or 1 replaces every occurrence of that string in an error message. Messages stay safe but can become unreadable. The check could be limited to passwords of some minimum length, or the message could be redacted by position.
Security
No leaks found in the code I read. Debug output for DatabaseLogins only prints counts. Driver errors are redacted at the connect, query and reconnect boundaries and still keep DataError::Login. The remembered_database_* tests check for a leaked sentinel.
Performance
Medium (inline):resolve_project in crates/engine/src/cmd/connection_logins.rs is now called from connection.new, duplicate, edit, remove and add_layer_text. It can open blocking database connections on the calling thread, which is the UI thread on desktop. A transport failure, unlike an auth refusal, never marks the connection rejected, so a down server is retried on every one of these commands.
Quality
Low-medium (inline):clear_active and restore_active act on a process-global static in crates/data/src/source/duckdb.rs. project::reset now calls them, so engine tests that run in parallel can clear the activation a packet test is relying on. That could make the remembered_database_packets tests flaky.
Nit:connection_use::tables and connections::login both reset activations with the same set_connection_password(.., None); drop_activation(..) pair. A single helper would keep the two copies from drifting apart.
Nit: In crates/data/src/source/duckdb.rs, remember_password and set_connection_password overlap, and has_password, has_explicit_password and has_connection_password all answer similar questions. A short doc table of which one to use when would help.
AGENTS.md
Panic rules: the non-test code I read uses no unwrap, expect or panic. The panic! calls are in #[cfg(test)] modules.
Hostile-params test: hostile_params_never_panic gained junk remember and password cases.
wasm: the new engine code is gated with cfg(target_arch = "wasm32"), and connection_browse no longer needs its own desktop-only stub.
Translation: UI strings use tl!. No i18n/*.tsv changes are required.
Not checked: cargo xtask ci and ATTRIBUTION.md (this PR adds no assets and no dependencies).
Change size
Compared: the whole PR against main (merge base 87bb73c to PR head 3cb95de)
This is a partial review. The diff is about 27 files and I read roughly the first 1,300 lines, which cover the data and driver redaction, the duckdb password cache, connection_use, connection_logins, connections.rs, and the items.rs and layer.rs edits. I did not read the UI crate, connections.rs in the engine crate beyond the diff, or the large test files. I did not build or run anything.
Bugs
Medium confidence: a refused typed password stays as that connection's session password. In crates/engine/src/cmd/connections.rs (login, line 406), the typed password is stored with set_session_password before the reopen. If the server refuses it, credential() keeps returning it on later resolves and Browse calls. connection_use::tables avoids this with try_connection_password. Posted inline.
Medium confidence:login drops the current activation too early. It calls set_connection_password(.., None) and drop_activation before the "password is required" and credential()? early returns. A failed connection.login {id} with no password therefore silently deactivates a working login for that address. Posted inline.
Low confidence:redact_secret replaces every occurrence of the password in error text. A very short password such as "a" would garble unrelated driver messages, though it never leaks. Acceptable, but you could skip redaction below a minimum length or note it in a comment.
Security
No leaks found in what I read. Secret wraps the cached passwords, errors are redacted on the postgres, mysql and sqlserver paths, and the Io variant is handled including fragmented messages.
Low confidence:database_key(&c.address) is used with the raw address in request_password, but groups uses sources::redact(db). Confirm that both produce the same key for addresses that embed a password.
Performance
Nothing significant. resolve_keys limits reconnects to the affected databases. groups rescans all layers on each call, which is fine at normal project sizes.
Quality
connection_use::tables mixes session bookkeeping and I/O in one long function. Splitting credential selection from the read and error handling would make it easier to test.
The repeated json!({"label", "schema", ...}) mapping is duplicated across the three drivers in read_tables. A small helper would remove it.
redact_secret and the Entry/LazyLock cache are well documented and tested.
AGENTS.md
The unwrap_used lint is respected in non-test code. Test modules carry #[allow(clippy::unwrap_used)]. The panic! inside let ... else in secret_redaction_tests is test-only, so it is fine.
Wasm gating looks consistent: cfg(target_arch = "wasm32") stubs exist for the new helpers.
The new connection.forgetPassword command is in the engine, as the architecture requires. The new interface strings in ui-egui should use tl! and i18n::fmt; I did not check that.
The hostile-params test (hostile_params_never_panic) should cover connection.forgetPassword. I did not confirm that it does.
Change size
Compared: the whole PR against main (merge base 87bb73c to PR head 5b0d7d9)
This PR adds opt-in remembered database passwords. They are stored in the OS secret store inside a per-definition envelope. It also adds connection.forgetPassword, ID-based login resolution, and password redaction in driver errors. The design is careful, and the tests cover it well, including transactional delete, envelope mismatch and approval gating. I read the diff for the data, engine and assistant crates and for the connection commands. I did not read the UI, docs or the larger new test files in detail. I could not run the build or tests.
Bugs
Medium:delete_account (crates/engine/src/cmd/connections.rs:240) calls the secret store even when the connection never saved a password. A locked, denied or unavailable keychain therefore blocks connection.edit (address change) and connection.remove for unrelated connections. When there is no store, a connection that is still marked remembered, which is persisted, can never be removed or retargeted.
Medium-low:reopen (crates/engine/src/cmd/connections.rs:322) stops retrying after a refusal only for saved passwords. A refused typed password is retried on every remaining layer of that database, which sends repeated failed logins and risks account lockout.
Security
Low-medium:DataError::redact_secret (crates/data/src/lib.rs:76) only matches the literal password. A percent-encoded or escaped echo from a server or driver would survive. One- or two-character passwords also over-redact unrelated text.
No leaks found in the new code. The envelope binds each password to its kind and address, so a reused ID never gets another server's password. Debug on DatabaseLogins prints counts only. The tests assert that nothing leaks into the project text or the assistant output.
Performance
Low:resolve_project and resolve_keys open layers synchronously, and they now run from connection.new, duplicate, edit and remove, as well as on project open. An unreachable database or a slow keychain prompt can block the command (the UI thread in the app). Low confidence, since I didn't trace the threading.
Quality
Low:connection_use::tables clears another connection's activation and selection before credential(...)? can fail. An early error therefore leaves the session changed.
Low: The global PASSWORDS map in duckdb.rs is keyed by address, and try_connection_password restores the previous entry after an attempt. A concurrent change to the same address during the attempt would be overwritten.
AGENTS.md
No violations found in the changed code. The code uses no unwrap/expect/panic outside tests, and the wasm paths are cfg-gated. connection.forgetPassword is added to the plugin NEVER list, there is an assistant approval test, and the hostile-params list gains junk remember values. I did not check whether cargo xtask notices or deny.toml need an update. I saw no new dependencies in the portion of the diff I read.

I read the full diff for the Rust engine, data and UI changes (diff lines 1–3060, which includes all of connections.rs, connection_use.rs and connection_logins.rs). I did not read ui-egui/tests/remembered_database/mod.rs, the smoke.rs change or docs/user-guide/data.md, and I read only the first part of the 539-line remembered_database_packets.rs. Nothing was compiled or run. The design is careful overall:
Passwords are stored in a Secret and never serialised into the project or the connections JSON.
The stored envelope is bound to the connection's kind and address, so a reused id can't pick up another server's password.
Errors from the Postgres, MySQL and SQL Server drivers are redacted, and DataError::Login keeps its kind through redaction.
Delete failures leave the connection list unchanged.
The assistant treats connection.forgetPassword as needing fresh approval.
Bugs
Refused typed password stays cached (crates/engine/src/cmd/connections.rs:342, medium confidence). When the server refuses a typed password, reopen doesn't clear the driver slot or the activation that login set just before. The saved-password branch does clear them. A later layer open or Refresh could resend the refused password. This contradicts the comment in login that a refused password "is not this session's credential".
Locked keychain blocks edit and remove (crates/engine/src/cmd/connections.rs:241, medium confidence). delete_account calls the store whenever one exists, even if the connection was never remembered. With a locked or denied keychain, a never-remembered connection can't be removed, and its address can't be edited.
Possible clobbered slot in try_connection_password (crates/data/src/source/duckdb.rs:180, low confidence). The lock is released during run(). If another thread changed the slot in that window, the failure restore would overwrite it. The risk is small, because these commands run on one thread.
Security
No leaks found. Passwords are not in notices, errors, JSON output or the project text. The tests assert this for the project text and connections JSON, notices, layer errors and the assistant's reply.
Opening a project can send a saved password automatically. It goes only to the exact driver address of a saved, remembered connection, and ambiguous matches ask the user instead.
A password of one or two characters would be replaced everywhere it appears in an error message. That only degrades the message text.
Performance
resolve_project runs a blocking connection attempt per remembered database every time a project opens or is imported. This is the same blocking pattern as before, now automatic. A slow or down server could freeze the UI for the connect timeout. Attempts are limited to one per database, and edits only retry the databases they affect.
Quality
Subprocess test harness (crates/engine/src/tests/remembered_database_packets.rs, around line 2254, medium confidence). isolated re-runs the test binary as a child process for each scenario and parses libtest's test result: line. This is fragile under nextest and renames, and it slows CI. A test-only reset hook for the process-global password map would be sturdier. I couldn't attach this as an inline comment because the line didn't resolve in the diff.
DataError::redact_secret rebuilds an Io error with io::Error::new, which drops its original source. This is acceptable since the message is all that's used.
AGENTS.md
No unwrap, expect or panic! in non-test code, and no unsafe. Lock poisoning is handled with into_inner.
The new remember parameter is validated as a boolean. The hostile-params test is extended with junk remember and id values.
New UI strings use tl!, and i18n::fmt is used in panes.rs.
The wasm path is cfg-gated, and connection.forgetPassword is added to the plugin NEVER list.
I couldn't check whether ATTRIBUTION.md, deny.toml or THIRD-PARTY-LICENSES.txt need updates. The diff adds no dependencies that I saw.

When a store is present, delete runs for every database connection, even one that was never remembered. If the OS keyring is locked or denied, connection.remove and an address-changing connection.edit fail with "The saved password couldn't be deleted" for connections that have no saved password at all.
Consider skipping the store call when !c.remembered. A stale account is then possible only if the marker was cleared by Absent without a delete, so it is worth deciding explicitly. The new transactional test only covers a remembered connection.
The reason will be displayed to describe this comment to others. Learn more.
Browse and Test of connection B (no typed password) unconditionally clear the address slot and drop_activation for that address. If saved connection A shares the address and is active, its layers lose their login on the next reopen or refresh. That matches the "no inferred identity" design, but it is a side effect of a read-only browse. If you want browse and test to leave other connections alone, restore the previous slot on failure, as try_connection_password does. Please at least check that this is intended.
I read the diff end to end except the remaining test files and the UI, docs and translation changes (diff lines 2200 onward). I did not build or run anything. The PR adds opt-in remembered database passwords: an OS secret store, per-connection identity, password redaction in driver errors, and project-open resolution.
Bugs
Store errors block removing or editing connections that never saved a password (medium). delete_account (crates/engine/src/cmd/connections.rs:241) calls the store's delete for every database connection whenever a store exists, not only when c.remembered is set. With a locked or denied keyring, connection.remove and an address-changing connection.edit fail with "The saved password couldn't be deleted". The new transactional test only covers a remembered connection. I posted an inline comment.
Browsing or testing one connection clears another's login (low-medium). In connection_use::tables (crates/engine/src/cmd/connection_use.rs:37), a Browse or Test with no typed password clears the address slot and activation unconditionally. Another saved connection that shares the address loses its login, so its layers stop opening on the next refresh. This fits the "no inferred identity" design, but it is a side effect of a read-only action. I posted an inline comment.
Security
No leaks found. Passwords sit in Secret and DatabaseLogins' Debug only counts them. The store holds an envelope that binds kind and address, so a reused sequential id cannot pick up another server's password. redact_secret is applied on the postgres, mysql and sqlserver error paths and in connection.test. The new connection.forgetPassword is added to the plugin NEVER list, and the assistant test requires fresh approval for it. Redaction replaces every occurrence of the password in the message. A very short password could mangle unrelated text in an error message (low, cosmetic).
Performance
Nothing significant. resolve_keys limits reconnection to the affected databases. redact_secret allocates only when the message holds the password.
Quality
connections.rs and connection_use.rs repeat the same json!({"label", "schema", "name", "column", "kind"}) mapping three times, once per driver. A small shared helper or a trait would cut that.
login() is now long, with several cfg branches and an ordering that matters (typed versus saved versus address-typed). A short comment or a split would help future maintainers.
The loggedIn field changed meaning, from "address has a password" to "this id has a known password". The tests were updated, so this looks intentional. It is worth a mention in the docs and changelog, and the docs/user-guide/data.md changes may already cover it.
AGENTS.md
No unwrap, expect or panic! in non-test code. The panic! calls in data/src/lib.rs tests are allowed by clippy.toml.
The wasm paths are cfg-gated, and hostile_params_never_panic gained junk remember parameters.
I did not verify the following:
cargo xtask ci, the layer check and cargo xtask notices, since no new dependency was visible in the part I read.
The i18ntl! usage in the UI changes.
The ATTRIBUTION.md and THIRD-PARTY-LICENSES.txt refresh.

PASSWORDS is process-global, but clear_active() (forget_connection_passwords) is now called from project.open, import_maps, add_layer_text and others. With more than one Session in a process (the engine test suite runs tests in parallel threads; the Python bindings can hold several sessions), one session opening a project wipes the activated passwords of every other session. The restore_active that follows only restores the calling session's activations. The engine's remembered_database* tests can therefore flake when they run concurrently with tests that open projects. Confidence: medium. Consider keying the cache by session, or scoping the clear to the ids this session owns.
The reason will be displayed to describe this comment to others. Learn more.
Redaction is by plain substring. A very short or common password (for example a or 1) will mangle unrelated error text ("conn********ction refused"). It also misses encodings a driver may echo, such as the URL-encoded form in a connection URI. Acceptable as a best effort, but consider documenting the limit. Confidence: low.
I read roughly the first 1,750 of the diff's 3,663 lines. That covers the data-layer redaction, the duckdb password cache, the engine connection commands (connections, connection_use, connection_logins, items, project, layer) and the first half of crates/engine/src/connections.rs. I did not read the rest of that file, the UI crate changes (connectionui.rs, panes.rs, sourcespane.rs), the packet and integration tests, or the docs. The findings below are limited to what I read.
Bugs
Browse and Test can drop another saved connection's working password (crates/engine/src/cmd/connection_use.rs:629, medium). Without a typed password, tables() removes whichever saved connection owns the address slot and drops its activation. If the connection being browsed then has no usable credential, the working password is lost.
The password cache is process-global, but clear_active() is now called on every project open, import and layer add (crates/data/src/source/duckdb.rs:170, medium). With several Sessions in one process (parallel engine tests, Python bindings), one session's open wipes the other sessions' activated passwords. This could make the new remembered_database* tests flaky.
A kind-only edit leaves the saved secret in the store (crates/engine/src/cmd/connections.rs:865, low). The account is deleted only when the address changes. A kind change clears remembered but leaves an orphaned secret in the store and stale session/saved caches.
Security
Error redaction is a substring match (crates/data/src/lib.rs:62, low). It is a reasonable best-effort defence against drivers echoing passwords. Very short passwords will mangle unrelated error text, and URL-encoded echoes are not caught.
Otherwise the design looks sound. The Secret type is used, the store envelope binds kind and address, connection.forgetPassword is in the plugin NEVER list, the assistant requires fresh approval for it (with a test), and the lock is not held during network I/O.
Performance
Nothing significant. groups() and resolve() rescan all layers per call, which is fine at normal project sizes. resolve_keys restricts re-resolution to the affected databases.
Quality
connection_use::tables and connections::login repeat similar activate, reject, drop-activation and request-password sequences. A shared helper would lower the risk of the two paths drifting apart.
The redaction code and its tests are clear, and they use the repo's clippy.toml test allowances correctly.
AGENTS.md
No unwrap, expect, panic! or unsafe in non-test code, as far as I read. The wasm cfg gating looks consistent. The new connection.forgetPassword strings are command metadata, so they are not translatable text.
I did not check ATTRIBUTION.md, THIRD-PARTY-LICENSES.txt or the .tsv catalogs. I also didn't see cargo xtask ci results.

redact_secret replaces every occurrence of the password as a plain substring. A short or common password (1, a, pg, host) will mangle unrelated parts of the error text, for example connection to ******** refused. That makes the diagnostics useless, and it can also reveal the password's length and content by which characters get masked. Consider a minimum length for substring redaction, or redacting only when the whole token matches. Confidence: medium-low. The leak protection is worth having, so this is a usability and precision concern.
The reason will be displayed to describe this comment to others. Learn more.
try_connection_password releases the lock during run() and then restores previous on refusal. If another thread (another command, a background layer reopen, or another login) changes this address slot in between, the restore silently overwrites that newer entry, or removes it. The window is small, but a compare-and-restore would avoid it: only restore if the slot still holds the entry this call inserted. Confidence: low-medium.
I read the Rust changes in data, engine and ui-egui in full, plus the assistant test. I skimmed the large new test files (remembered_database*.rs) and the docs. I did not build the code or run any tests. The design is careful overall: passwords are held in Secret, the lookup is bound to the saved definition (kind and address), the session password is cleared on refusal, and the project's address-only origins are never matched by ID. I found no definite bugs or security holes.
Bugs
Race in try_connection_password (crates/data/src/source/duckdb.rs, inline comment). The lock is released while run() does network I/O. The restore on refusal then overwrites or removes whatever another thread put in that address slot in the meantime. Confidence: low–medium.
Test-typed password for an unsaved database (cmd/connections.rs, test(), the c.id.is_empty() branch). It goes through layer::database_tables with password. The password is then cached as an explicit address password in duckdb::remember_password, even if the server refuses it. This matches the earlier behaviour, but the new connection.test description says the password is "never persisted" and that a refusal restores prior credentials. The unsaved path doesn't do either. Confidence: low–medium.
Security
No leaks found. Errors from the postgres, mysql and sqlserver drivers are passed through redact_secret, and Debug for DatabaseLogins prints counts only. The only caveat is the short-password over-redaction under Quality.
Performance
Nothing significant. The resolve* loops call groups(s) over all layers. The scoped resolve_keys avoids reconnecting to unrelated databases on every edit.
Quality
Short secrets (crates/data/src/lib.rs, inline comment). redact_secret masks every substring match, so a password like 1 or host garbles unrelated error text. A minimum length or token-aware matching would help. Confidence: medium–low.
Remember checkbox reset (ui-egui/src/connectionui.rs, save()). After a failed or refused login, remember is reset to false together with the password. The user must tick "Remember on this computer" again when retrying and may not notice. I couldn't attach an inline comment to this line. Confidence: low.
connection_use.rs and connection_logins.rs repeat the "drop activation, then set_connection_password(key, id, None)" sequence in several places (login, tables, open_connection, resolve). A small helper would reduce drift.
Reopened carries #[cfg(not(wasm32))] refused but not the other fields, which is slightly inconsistent.
AGENTS.md
No unwrap or expect in non-test code, and the lock poisoning is handled with into_inner. The panic! calls are in test code only.
New UI strings use tl!. The new connection.forgetPassword command is added to the plugin NEVER list, which is right. The browser build compiles out the database paths with cfg(target_arch = "wasm32").
The hostile-params test was extended with remember and object-valued id. I did not see a regression test for the unsaved-database test() path.
If the PR added new dependencies, run cargo xtask notices. The diff doesn't show any.

Summary
A named PostGIS, MySQL/MariaDB or SQL Server connection can keep its password in the operating
system's password store (macOS Keychain, Windows Credential Manager, the Secret Service), behind
an unchecked Remember on this computer opt-in in the new, edit and login forms. Nothing is
saved unless that is checked, Test never persists anything, and the browser and the command
line stay session-only.
Lifetime is bound to the definition, not the address. The store holds an envelope of the
connection's kind, cleaned address and password under
connection/<id>, and it is only used whenit still matches the saved definition. Ids are sequential (
c1,c2), so a reused id, a staleaccount from reset preferences or an interrupted address edit can never attach an old password to
a new server. Renaming or regrouping keeps the password; changing the address or username, or
removing the connection, deletes the old account first and leaves the definition unchanged if
that fails. Duplicating copies neither the stored password nor the session login. A corrupt or
mismatched envelope clears the remembered marker and sends nothing.
Projects stay address-only. Opening one resolves each database by its exact driver address:
one remembered match reconnects automatically, several queue a chooser with no default, and none
keeps today's password-free behaviour. Only the wrapper, outer whitespace and password are set
aside — URI and libpq forms, reordered parameters, host aliases and different usernames are not
treated as the same server. Precedence is explicit session input or selection > saved password >
existing ambient fallbacks, and opening a project still never newly authorizes
PGPASSWORD,MYSQL_PWD,SQLCMDPASSWORD,~/.pgpassor Windows integrated sign-in. A password the serverrefuses is suppressed for the rest of the session without touching the stored value; replacing it
takes a new login with Remember checked. Ambient fallbacks and the drivers' existing
ask: falseprotection are untouched.
Command surface (the part worth a maintainer's eye, since it changes an existing command):
connection.logingains an optional"remember"boolean (defaultfalse, rejected fornon-database kinds) and now accepts
{"id"}with no password, which explicitly selects thatconnection's existing session or remembered password. A
remember:truelogin also returns"passwordSaved", and"warning"when a store couldn't keep a usable password.connection.forgetPassword {"id"}is new: it deletes the stored value and clears the marker,leaving an explicitly entered session password and already-open layers alone. It never selects an
inactive connection or replaces another connection's or an unowned address's active password.
connection.listreports"remembered", per-id"loggedIn"(no longer attributing an address'scache entry to every connection at that address; includes an already-loaded remembered password,
without reading the store during listing, and does not claim authentication succeeded) and a
secret-free
"loginRequests"array(reason, database label, candidate ids, affected-layer count) that scripts and the assistant can
act on with
connection.login {"id"}..rgisis unchanged: no format change, no connection ids in the project. No new dependency, sodeny.tomland the third-party notices are unaffected.The other half of the change is containment: the driver's active-password slot now records which
saved id activated it, so switching to
c2cannot inheritc1's password and clearing for aproject load preserves explicitly typed ones;
connection.forgetPasswordis reserved to the user(plugins cannot run it, the assistant asks each time); and driver errors are redacted of the
active password at connect, query and reconnect boundaries while keeping
DataError::Login, so aserver that echoes the password cannot put it in a notice, a layer's error or a command result.
Testing
cargo xtask ci(fmt,clippy -D warnings, the whole workspace suite, layers) andpre-commit run --all-filespass on the rebased tree.On
b5ab090, CI alsopassed Rust tests and layering on Linux, macOS and Windows, the browser build, lint, licences
and notices. The Python package run
passed too, including Windows Python 3.14. Release-app builds were skipped (no
ci:fulllabel).These CI results do not claim live Windows/Linux OS-store verification.
Plus:
cargo test -p rustgis-engine remembered_database_(20 tests) drivesa loopback PostgreSQL handshake and asserts the bytes the driver actually sends: a unique exact
saved match sends the saved password and only once per source group; another host, port, user,
URI form or reordered address sends nothing; an explicitly typed address password wins; a saved
password wins over an ambient

not overwrite it, a checked one does. A transport failure or a missing table is not reported as
a wrong password. The review regressions additionally exercise inactive-connection Forget,
active versus unowned driver-slot ownership, saved-only activation cleanup, and per-id status.
A named Test that receives a positive authentication refusal restores the previous session
password, selection and exact driver-slot owner/value (or removes an attempt with no prior
credential). Successful authentication followed by a listing error keeps the new session
password. Neither Test path writes the store. Both subprocess helpers require exactly one
passing, non-ignored child test, not merely a successful exit.
authenticates but whose catalogue read fails stays re-resolvable: the loopback server sees the
connect from the project open, sees nothing after
connection.newfor a different address, andsees the connect again after
connection.new/connection.removeat that same address. Revertingthe scoped resolver to a full resolve fails the test with an unexpected password packet.
connection.loginis sent but is not kept as thatid's session credential, so it is not reported as available and cannot be reused by a later
resolve or Browse; and a login that turns out to have no password of its own fails without
deactivating the password another connection is using for that address; and a refused attempt is
made once per database rather than once per waiting layer, typed or saved.
Confirmed typed-login refusals restore the previous driver password and owner, selection and
activation; with no previous slot, the attempted password is removed. Packet regressions
verify the next driver read for same-ID, other-ID and unowned address credentials, plus the
empty-slot case. A standalone native smoke exercised all four cases.
Separately, refusal of a reused cached-session password evicts that session value, its driver
entry and activation. An equivalent saved value is also suppressed for that session; a
different saved value is not marked refused. This includes invalidated saved-cache cases and
leaves the OS-store entry unchanged. Packet regressions verify
eviction and no resend on a password-free retry through login, Test, Browse and project open;
authenticated listing failures retain the credential. A native smoke exercised both outcomes
through those four entry points.
