Verify OS Platform Compatibility for Backup Restoration

Microsoft Authenticator backups are platform-specific and cannot be transferred between different operating systems like Android and iOS.

Microsoft Authenticator restricts backup restorations to the same operating system platform. If your lost phone was an Android device and your new replacement phone is an iPhone (or vice versa), the backup cannot be recovered.

To successfully restore your stored credentials, you must use a replacement device running the exact same operating system as the phone you lost.

Use a compatible device

Obtain a replacement device that uses the identical operating system (Android or iOS) as your lost phone.

Install the app

Download and install the Microsoft Authenticator app from the official Google Play Store (for Android) or Apple App Store (for iOS).

Initiate recovery

Open the Microsoft Authenticator app on the new device and tap on 'Begin Recovery' at the bottom of the screen. Do not log in using the standard sign-in button first.

Sign in to your account

Platform Limitation: If you permanently switched platforms (e.g., from Android to iOS), you cannot use the cloud backup. You will need to manually re-add each of your accounts by logging into those services with alternative 2FA methods and scanning new QR codes.

Frequently Asked Questions

Can I recover my Authenticator accounts if I switched from Android to iPhone?

No. Microsoft Authenticator backups are not cross-platform compatible. You cannot restore an Android backup on an iOS device or vice versa. You will need to recover your accounts manually on the new platform by setting up 2FA again with each service provider.

What should I do if I don't have access to my lost phone to turn off cloud backup?

You do not need the old phone to restore a backup to a new device of the same operating system. Simply select 'Begin Recovery' upon opening the Authenticator app on the new device and sign in with your recovery account.

Why isn't the 'Begin Recovery' option finding my backup?

This usually happens if you are signed into a different Microsoft account than the one used for the backup, or if you are using a device with a different operating system. Ensure both the account and the OS platform exactly match the original setup.
