To recover your Microsoft Authenticator backup, ensure that you have a stable internet connection, as the recovery process requires it. If the backup option is greyed out, it might indicate that the backup feature was not enabled before you reset your phone. Unfortunately, if you did not have the cloud backup enabled prior to the reset, it may not be possible to recover your accounts linked to the Authenticator app.
Here are some steps you can try:
- Check Internet Connection: Make sure your device is connected to a stable Wi-Fi or mobile data network.
- Reinstall the App: Sometimes, uninstalling and reinstalling the Microsoft Authenticator app can help resolve issues. After reinstalling, try to recover your backup again.
- Enable Cloud Backup: If you can access the settings, ensure that the cloud backup option is enabled for future use.
- Manual Recovery: If you have recovery codes for your accounts, you can use those to regain access to your accounts directly without the Authenticator app.
If these steps do not resolve the issue, you may need to contact Microsoft support for further assistance regarding your specific situation.
