Authenticator is no longer available.

Question

Thank you for your help.
When I changed my iPhone model, I didn't take over the Authenticator app, so I couldn't use Authenticator, I couldn't sign in to my Microsoft account, and I couldn't use all MS services. Please let me know where to find the solution. Thank you.

Answer 1

I'm the 365 admin on my work account, but I can't reset my MFA device without being able to sign in to any of my accounts.

If you are the only global admin on the account and are blocked entirely, you can reach out to the Azure Data Protection team to restore access. 866-807-5850

You can restore from 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 turned on or off at the service provider end.

I tried to restore from iCloud backup, but it was not turned on and could not be restored.

I asked MS support to perform a security reset and reset the authenticator app to solve the problem.

Thank you to everyone who responded.
