Got a new phone and can't get the request for the authenticator as its going to the old phone.

Question

I got a new phone and didn't transfer my authenticator over. Now when asked to approve the request it goes to the old phone which I no longer have. What can I do?

Answer 1

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.
