I had to clean my cellphone and when i reinstalled my authenticator app and activated my backups all of my acounts that used 2 factor codes on the authenticator were gone, only my microsoft account were there.

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.

Answer 2

Hello, I tried to recover as you said, but when I do this it says that my backup is not stored at my e-mail adress, and asks to enter with another microsoft account. My app is set in portuguese, hope that you understand.

Answer 3

You backup recovery account should be a microsoft personal account. If for whatever reason the restore is unsuccessful, then you'll need to work with the service provider about accunt recovery.

So i will have to speak to every app staff to deactivate the 2 factor? And if they say that they can not do it i will have to create another account?
