I backed up my data to Authenticator, but all the backup data was lost. I absolutely need the backup data; can you help me?

It must be backup data created before 202626/06/12.

    Backup data in Microsoft Authenticator can only be restored if it still exists in the associated cloud backup location and the required conditions are met. If the backup itself has been deleted, overwritten, or is otherwise no longer present in iCloud (iOS) or Microsoft cloud backup (Android), it cannot be recovered.

    Key points from the documented behavior:

    1. Authenticator backups are stored per platform and cannot be restored across device types:
      • iOS backups (via iCloud) cannot be restored on Android.
      • Android backups (Cloud Backup) cannot be restored on iOS.
    2. For iOS backups:
      • iCloud Drive, iCloud Keychain, and iCloud Backup must be enabled on the device where the backup was created.
      • Authenticator must be listed and enabled in the iCloud “Saved to iCloud” list.
      • To restore, a device must be signed into the same iCloud account, with iCloud Drive/Keychain/Backup enabled, and Authenticator installed. Then sign in to each account in Authenticator to complete the restore.
    3. For Android backups:
      • Cloud Backup must be turned on in Authenticator and tied to a specific Microsoft personal account.
      • If the backup was deleted (for example, by turning off Cloud Backup and confirming deletion, or by changing the backup account), that backup is no longer available.
    4. What is actually backed up and restored:
      • Microsoft personal accounts using only one-time password (OTP) codes: OTP configurations are restored if the backup exists.
      • Microsoft personal accounts using passwordless sign-in: only the account name is backed up; sign-in must be reconfigured after restore.
      • Work or school accounts: only the account name is backed up; sign-in must be reconfigured.
      • Third-party accounts (Amazon, Facebook, Gmail, etc.): OTP configurations are restored if the backup exists.

    If the backup data created before 2026-06-12 no longer appears when attempting to restore (for example, no backup is listed, or the restore process finds nothing), then that backup is not available in the service and cannot be recovered. In that case, accounts must be re-added manually using their original QR codes or recovery procedures from each service (Microsoft account recovery, work/school IT helpdesk, or each third-party site’s 2FA recovery options).

    For iOS specifically, if the backup does not appear on a new device, the documented troubleshooting is:

    1. On the original iOS device (where backup was created):
      • Ensure iCloud Drive is enabled.
      • Ensure iCloud Keychain is enabled.
      • Ensure iCloud Backup is enabled and that “Authenticator” is toggled on in the Saved to iCloud list.
      • Ensure Authenticator is updated to version 6.8.33 or later.
      • Open the app at least once before switching to the new phone.
    2. On the new iOS device:
      • Uninstall and reinstall Authenticator.
      • Then attempt to restore again.

    If these steps still do not surface the backup, the backup is effectively lost and cannot be retrieved.
