Microsoft Authenticator on iPhone 13 Pro (iOS 17) not receiving notifications after app was offloaded

Question

My iPhone 13 Pro (iOS 17) offloaded Microsoft Authenticator when my phone ran out of disk space. I reinstalled it, but now it won't receive any notifications, even if I check manually in the app. This is not an issue with my phone settings or DND. Can someone help me solve this problem? Thanks.

Also this issue effects both my personal and work accounts!

Answer 1

You can restore from an authenticator cloud backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake. https://support.microsoft.com/en-us/account-billing/back-up-and-recover-account-credentials-in-the-authenticator-app-bb939936-7a8d-4e88-bc43-49bc1a700a40

Without a backup to restore from the only option is to work with each of the service provider's account recovery methods. The authenticator app is nothing more than a code generator. The two factor is only turned on or off at the service provider end.

Answer 2

Sounds like you'll need the work admins to reset the account so a new QR code can be generated with which you can relink the authentication device to your account.
