Description

Linear: MOBILE-667 (Expo part). Android side: clerk/clerk-android#1097.

From April 2027, Google Play requires apps with sign-in to keep users signed in when they move to a new Android device (Restore Credentials). Expo apps that use the prebuilt native AuthView had no way to turn this on.

This adds an opt-in enableRestoreCredentials?: boolean prop (default false) to AuthView:

<AuthView enableRestoreCredentials />
  • JS/TS: the prop is declared and documented on AuthViewProps (Android only, opt-in, needs passkeys enabled on the instance). @clerk/expo/native-components re-exports these types, so it needs no change.

  • Android: ClerkAuthViewModule gets an enableRestoreCredentials view prop and passes it to the Compose AuthView(enableRestoreCredentials = ...) from clerk-android fix(clerk-js): Form errors not displayed when form submitted with enter #1097. With it on, a signed-out AuthView tries the restore credential that device setup transferred, but only on the first launch after the app is installed or restored onto a device. After sign-in or sign-up it creates a restore credential for the signed-in user in the background. That replaces the one this device created for the same user before, and the device's single restore credential belongs to the most recent user. It needs passkeys enabled as a first factor.

  • Sign-out: a sign-out from JS doesn't go through the native SDK's sign-out, so before this it left the device's restore key in place. ClerkExpoModule now watches Clerk.clientFlow and calls Clerk.restoreCredentials.clear() when a user who was signed in (active or pending) is no longer signed in on the client, whichever side ended it. That matches native signOut(sessionId), which clears the key even when other sessions remain. The check is ClerkSignOutDetector, which:

    • compares signed-in users rather than sessions, so a device-token swap to a client where the same user is signed in keeps the key;
    • skips clients that have no id yet (the null from a reset, the empty Client() during a device-token swap) and keeps the last real client across them, so a configuration switch still clears the old instance's key;
    • skips a session that had already passed its expire_at, so a session that reaches its maximum lifetime keeps the key, as on native. FAPI leaves non-active sessions out of the client, so an inactivity timeout or a revocation looks the same as a sign-out and still clears it.

    A failed clear is logged and not retried, as in the native SDK. The module's Kotlin tests need an Expo host project and aren't run in CI, so I ran ClerkSignOutDetectorTest by copying the detector and test into clerk-android 1.3.0's :source:api unit tests (5 passed).

  • iOS: the prop is accepted and ignored. AuthView only forwards it to the native view on Android, so the iOS view definition is unchanged.

Main now pins clerk-android 1.3.0, which includes enableRestoreCredentials (clerk/clerk-android#1097, released in 1.2.0), so no version bump is needed here. I haven't compiled the module in an Expo app or run it on a device.

Possible follow-up: standalone JS APIs for restore credentials (create / sign in / clear) outside of AuthView. Those need a design for syncing auth state between the native SDK and the JS client, so they're not in this PR.

Walkthrough

AuthView adds an enableRestoreCredentials prop that defaults to false and is forwarded to the native view on Android. The changes document its first-launch restore behavior and passkey requirements. Android client synchronization now detects qualifying sign-outs and attempts restore-credential cleanup. Tests cover prop forwarding and the sign-out detector’s session and expiry cases.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Possibly related PRs

  • clerk/javascript#10594: Updates the clerk-android dependency pins, changing the SDK contract used by the restore-credential integration.

Merge Risk: Low · up to ea4d4

The change is low risk overall, but the restore-cleanup race and missing public documentation should be addressed before or alongside release.

Explanation

The title "feat(expo-native-components): opt-in Restore Credentials for the Android AuthView" matches the main change. The PR adds an opt-in enableRestoreCredentials prop to the Android AuthView, and the changeset covers the JS, Android view, and sign-out detector changes. It is specific and scoped to the Expo native components package. It does not cover the sign-out detector, but that is secondary and expected.

Full details: Description check

Explanation

The description is related to the changeset. It explains the new enableRestoreCredentials prop on AuthView, the Android view wiring to clerk-android, the iOS no-op behavior, and the ClerkSignOutDetector added for sign-out cleanup. It also lists the tests run and the limits of verification.

commit: ea4d430

…the restore key on JS sign-out

Match the final clerk/clerk-android#1097 behaviour in the AuthView TSDoc and the changeset: restore is tried only on the first launch after install or restore, the device's restore key belongs to the most recent user and replaces that user's previous one, and passkeys must be a first factor.

When a JS-originated client sync takes the client from having sessions to none, call Clerk.restoreCredentials.clear() so a JS sign-out deletes the device's restore key like a native sign-out does.

…in session ends

Watch the native client instead of comparing it around a JS-requested
refresh, so a sign-out that native sees first still clears the key, and
clear it when any signed-in session ends, as native signOut(sessionId) does.

This looks good to me. Pinning clerk-android 1.3.0 (which has AuthView(enableRestoreCredentials)) and resolving the merge conflict cleared what was blocking it. Watching clientFlow holds up better than comparing the client before and after a JS refresh. I checked these against the 1.3.0 SDK sources:

  • Auth.signOut(sessionId) clears the key even when other sessions remain, so the parity claim holds.
  • Clerk.reset() sets the client to null without ending any session, so ignoring null is correct.
  • RestoreCredentials.clear() catches everything, so the watcher can't crash.

None of the three inline comments block merging. The expiry one is the one I'd most like an answer on.

Compare signed-in users instead of sessions, skip clients that have no id yet,
and leave sessions that passed their expire_at alone.

Before, the prop never reached the native view. After, Android gets false by default and true when set, and iOS gets nothing.

Prevent stale restore-credential cleanup from affecting a later sign-in.

When this condition returns true, ClerkExpoModule starts clearRestoreCredential() in a separate coroutine. A new signed-in client can arrive before that cleanup completes. The cleanup can then cancel the new credential's creation or clear the credential after it is created.

Track and await cleanup before processing the next client state, or cancel or guard stale cleanup when a newer signed-in client is observed. Add a test for sign-out followed immediately by sign-in.

at line 17:
Prevent stale cleanup triggered by ClerkSignOutDetector from racing with a newer
signed-in client: coordinate clearRestoreCredential() in ClerkExpoModule so the
next client state is processed only after cleanup completes, or ensure cleanup
is canceled or guarded when a newer signed-in client arrives. Add a test
covering sign-out followed immediately by sign-in and verify the new credential
remains intact.
