Backend storage, middleware, routes, frontend flows, tests, deployment, and documentation were updated for username-based authentication and Better Auth persistence. ChangesBetter Auth integration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The authentication migration still risks misleading authorization failures in six sign-in flows, reduced brute-force protection when NODE_ENV is unset, and broken OIDC redirects for upgraded installations. These security and upgrade-compatibility issues make the PR unsafe to merge without fixes or explicit acceptance. Sequence Diagram(s)sequenceDiagram

insertKnownColumnssilently discards any value whose column is missing from the table.seedBetterAuthUserpassesroleandpermissions, andassertBetterAuthCoreSchemadoes not check those columns.

Inline comments:
In @.tests/auth/auth-adapters.test.js:
- Around line 128-131: Update the test around getLocalNetworkBypassStatus and
resolveLocalNetworkBypassUser to assert the expected enabled state directly and
assert the resolved bypass user unconditionally, including the expected user id
41; remove the status.active guard and avoid comparing two computed values.
In @.tests/auth/better-auth-migration.int.test.js:
- Around line 109-117: Re-read the credential row after the sign-in request in
the migration test, then assert the password hash contract against that fresh
database value rather than the pre-login credential object. Align the assertion
with the intended authentication behavior, including the expected scrypt rehash
if that contract applies, while preserving the existing login and user identity
checks.
In @.tests/auth/lidarr-preferences.int.test.js:
- Around line 228-236: Validate sign-in responses and bearer tokens in every
migrated helper: in .tests/auth/lidarr-preferences.int.test.js lines 228-236,
assert the token in loginAsAdmin; in .tests/auth/navidrome-settings.int.test.js
lines 83-88 and .tests/auth/quality-profile-settings.int.test.js lines 41-46,
add status and authToken assertions; in
.tests/subsonic/subsonic-canonical.int.test.js lines 240-245, add both
assertions while preserving authToken reuse; in
.tests/users/plex-global-account-owner.int.test.js lines 44-52, include the
response body in the status assertion and validate the token; and in
.tests/users/plex-link-routes.int.test.js lines 29-37, validate the token before
returning it.
In `@backend/db/helpers/users.js`:
- Around line 14-15: Update userOps.getAllUsers to include the selected name and
email fields from getAllUsersStmt in each returned user object, allowing the
settings list to use profile values instead of falling back to username.
In `@backend/routes/health.js`:
- Line 236: Update the GET / handler to await buildBootstrapPayload before
assigning library, discovery, websocket, and system fields or serializing the
response, preserving all bootstrap payload properties in the JSON output.
In `@backend/routes/onboarding.js`:
- Around line 172-190: Update the administrator provisioning flow around
userOps.countUsers and auth.api.signUpEmail to locate an existing administrator
account or repair the partially created account before completing onboarding. If
sign-up created a user but role promotion failed, retry updating that user to
role "admin" on subsequent /complete requests; only call
dbOps.updateSettings(nextSettings) after an administrator is confirmed, and
preserve the existing failure response when repair cannot succeed.
In `@backend/routes/users.js`:
- Around line 193-212: Update the user-creation handler to read permissions from
req.body.data.permissions, matching the frontend request shape, while preserving
the existing default-permission merge and null behavior when permissions are
absent. Keep the createUser payload and validation flow unchanged.
- Around line 308-310: Update backend/routes/users.js lines 308-310 to pass
server request headers via fromNodeHeaders(req.headers) to
auth.api.setUserPassword, and update lines 562-563 similarly for
auth.api.removeUser. Update backend/scripts/resetAdminPassword.js lines 117-119
to use the trusted server-side password-reset helper or provide the required
authoritative session headers for the existing-user password update.
In `@backend/scripts/resetAdminPassword.js`:
- Around line 140-142: Update the resetAdminPassword success output to stop
printing the supplied password via the password log statement; retain only
non-sensitive confirmation details, and print a password only when it was
generated by the script or otherwise explicitly required by the existing flow.
In `@backend/services/betterAuth.js`:
- Around line 108-117: Update getOidcPlugin() to enable overrideUserInfoOnSignIn
so mapProfileToUser(profile) recomputes and persists both role and permissions
on every sign-in, including when a user loses OIDC admin membership.
In `@backend/services/websocketService.js`:
- Around line 49-57: Update handleConnection to register a temporary close
listener on ws before the authentication await, track whether it fired, remove
it after authentication, and return if it fired or ws.readyState is not OPEN
before adding the socket to this.clients. Add an integration test covering a
socket closing while authentication is pending.
In `@docs/architecture/0002-better-auth.md`:
- Around line 7-14: Update the Better Auth table list in the architecture
document to use the physical users table name, users, instead of user. Verify
the remaining listed names match the physical tables configured by the Better
Auth mapping, without changing unrelated documentation.
In `@docs/src/content/docs/api/endpoints.mdx`:
- Around line 28-40: Document username-based Better Auth sign-in across all
affected sites: in docs/src/content/docs/api/endpoints.mdx lines 28-40, add POST
/api/auth/sign-in/username with its username-and-password request contract; in
docs/src/content/docs/admin/users.mdx lines 12-16, state that local users may
sign in with either email address or username; and in
docs/src/content/docs/api/overview.mdx lines 22-30, add a username sign-in
example or link to the username endpoint.
In `@frontend/src/pages/Login.jsx`:
- Around line 40-43: Update frontend/src/pages/Login.jsx:40-43 to build an
absolute frontend callbackURL, while keeping OIDC_REDIRECT_URI as the provider
callback. Update frontend/src/utils/api/endpoints/auth.js:58-63 and
frontend/src/pages/SsoComplete.jsx:42-47 so cross-origin startOidcLogin and
getMe requests include session credentials. Configure the API CORS middleware
with the frontend origin and Access-Control-Allow-Credentials, and use cookie
attributes compatible with cross-origin requests.

Heads-up: #813 looks likely to survive this migration unchanged, and its blast radius grows hereFlagging because this PR is the cheap moment to settle it, and after merge it becomes a second migration. #813 documents I checked this against this branch rather than inferring it, and the synthetic identity is still present at this PR's head ( The scope is wider here than on current
So the new Better Auth-owned tables inherit the same constraint while the identity that can't satisfy it is carried over. Every FK-inserting route reachable by API key is in scope, not just the Last.fm one.

What changed
Aurral now uses Better Auth for local credentials, sessions, OIDC, and user administration. Aurral-specific permissions, proxy/LAN/API-key/Subsonic/stream-token adapters, Plex linking, and application user IDs remain in Aurral.
Existing users are migrated in place: usernames, bcrypt passwords, roles, permissions, profile settings, relationships, and numeric IDs are preserved. Existing custom sessions are invalidated once, so users sign in again after upgrading. OIDC installations keep the legacy /sso/callback path as a compatibility alias.
Migration and rollback
This is a forward-only database migration. Back up /config before upgrading. Do not roll back by running an older Aurral image against the migrated database; restore the pre-upgrade backup if rollback is required. BETTER_AUTH_SECRET and BETTER_AUTH_URL are optional: Aurral persists a generated secret and derives the request origin when no URL is configured.
