A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If the Authenticator backup does not show any saved accounts after reinstalling, those deleted app authenticators usually cannot be recovered from Microsoft unless a valid backup already exists.
What can still be checked:
- Confirm the backup account is the same one used before.
- Authenticator backup requires the same recovery account used when backup was created.
- On iOS, backup also depends on the same iCloud account.
- If using iPhone, verify the old-device backup prerequisites were enabled:
- iCloud Drive
- iCloud Keychain
- iCloud Backup
- In Saved to iCloud, Authenticator must be turned on
- Authenticator should have been opened at least once before switching phones
- Authenticator version should be 6.8.33 or later
- On the new device, try the supported restore troubleshooting step:
- Uninstall and reinstall Microsoft Authenticator
- Then check whether the backup appears
- If backup was signed in with the wrong account, delete that backup and recreate it:
- Open Authenticator > Settings
- Under Backup, turn off Cloud Backup and confirm OK
- Turn Cloud Backup on again and select Continue or Change account
What is recoverable after restore:
- For third-party accounts such as game or social accounts, one-time password codes are restored only if they were included in the backup.
- For work or school accounts, only the account name is backed up, and sign-in is required again.
- For Microsoft personal accounts using passwordless sign-in, only the account name is backed up, and sign-in is required again.
If no valid backup appears, the remaining path is with the affected service, not Microsoft Authenticator. For third-party accounts such as Rockstar, the MFA secret/code must be reset by that service through its account recovery process. Microsoft Authenticator cannot recreate a third-party account’s lost authenticator entry when no backup is available.
