Hi NickD
You are correct Microsoft Authenticator backup on iPhone has specific limitations.
- On iOS, Microsoft Authenticator only supports backup to Apple iCloud, not directly to your Microsoft account like on Android.
You cannot back up Microsoft Authenticator data from an iPhone directly to Microsoft’s own cloud/account.
Additionally, backups are not cross-platform: accounts backed up on an iOS device cannot be restored on an Android device, and vice versa.
For more details, refer to Microsoft’s official documentation: Back up and recover account credentials in Microsoft Authenticator
Hope this helps. Do let us know if you any further queries.
