Description

On Android, user.id was the email address because GoogleIdTokenCredential.id is the account email, not the stable account ID. iOS already returns the OIDC sub. Android now decodes sub from the ID token so both platforms match.

No user impact. The user object never leaves @clerk/expo and the sign-in flow only forwards the ID token.

📝 Walkthrough

Walkthrough

Android Google sign-in now derives user.id from the Google ID token’s sub claim. The implementation decodes the token payload, reads a non-empty subject, and falls back to an empty string when extraction fails. The credential ID remains the source for the email. A patch changeset documents the behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk:🔵 Low · up to e8509

The Android sign-in flow now derives the stable Google account identifier from the token, but a parsing failure can still produce a successful result with an empty user ID. The change is otherwise localized and mergeable with explicit follow-up to reject invalid responses.

Description
On Android, user.id was the email address because GoogleIdTokenCredential.id is the account email, not the stable account ID. iOS already returns the OIDC sub. Android now decodes sub from the ID token so both platforms match.
No user impact. The user object never leaves @clerk/expo and the sign-in flow only forwards the ID token.
Resolves MOBILE-626

Description
On Android, user.id was the email address because GoogleIdTokenCredential.id is the account email, not the stable account ID. iOS already returns the OIDC sub. Android now decodes sub from the ID token so both platforms match.
No user impact. The user object never leaves @clerk/expo and the sign-in flow only forwards the ID token.

📝 Walkthrough
Walkthrough
Android Google sign-in now derives user.id from the Google ID token’s sub claim. The implementation decodes the token payload, reads a non-empty subject, and falls back to an empty string when extraction fails. The credential ID remains the source for the email. A patch changeset documents the behavior.
Estimated code review effort: 2 (Simple) | ~10 minutes
Merge Risk:🔵 Low · up to e8509
The Android sign-in flow now derives the stable Google account identifier from the token, but a parsing failure can still produce a successful result with an empty user ID. The change is otherwise localized and mergeable with explicit follow-up to reject invalid responses.

📝 Walkthrough
Walkthrough
Android Google sign-in now derives user.id from the Google ID token’s sub claim. The implementation decodes the token payload, reads a non-empty subject, and falls back to an empty string when extraction fails. The credential ID remains the source for the email. A patch changeset documents the behavior.
Estimated code review effort: 2 (Simple) | ~10 minutes
Merge Risk:🔵 Low · up to e8509
The Android sign-in flow now derives the stable Google account identifier from the token, but a parsing failure can still produce a successful result with an empty user ID. The change is otherwise localized and mergeable with explicit follow-up to reject invalid responses.

Description
On Android, user.id was the email address because GoogleIdTokenCredential.id is the account email, not the stable account ID. iOS already returns the OIDC sub. Android now decodes sub from the ID token so both platforms match.
No user impact. The user object never leaves @clerk/expo and the sign-in flow only forwards the ID token.
Resolves MOBILE-626
