Restore synced Google Authenticator codes by signing in on a new phone

Google Authenticator users can restore synced two-factor authentication codes on a new phone by installing the app and signing in with the same Google account. The cloud sync option, available since 2023, can make changing devices easier and help users regain access if their old phone is lost or damaged.

The feature requires Authenticator 6.0 or later on Android or 4.0 or later on iOS, with codes saved to the cloud. Users who prefer not to sync can transfer accounts manually using a QR code, but need their old phone. If neither option is available, they may need to recover accounts individually; Google backup codes can help prevent that problem.
