A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
To sign out of Microsoft Authenticator, all accounts must be removed. There is no separate sign-out button for a single signed-in account.
What to do:
- If the goal is to restore the original backed-up accounts, sign out first by removing accounts.
- To remove one account in Authenticator:
- Open Authenticator.
- Select the account.
- Tap the Settings gear.
- Tap Remove account.
- To remove all accounts, reset the app data:
- Android: Settings > Apps > Authenticator > Storage or Storage & cache > Clear data > OK
- iOS: Settings > General > Storage > Authenticator > Offload App
Important:
- This has no undo. All accounts will be removed, and the device will no longer be usable to verify sign-in until accounts are added back.
- If the wrong backup account was used, the backup can be deleted in Authenticator > Settings > under Backup, turn off Cloud Backup and confirm, then turn it on again and choose Continue or Change account to sign in with the correct backup account.
- For restoring backed-up credentials, select Restore from backup or Begin recovery before signing in. If already signed in, sign out first.
What is restored:
- Work or school accounts: only the account name is restored; sign-in is required again.
- Microsoft personal accounts with passwordless sign-in: only the account name is restored; sign-in is required again.
- One-time password accounts: codes are restored.
If the original backup account cannot be accessed, support cannot restore those credentials. In that case, the accounts must be added again.
