The Authenticator app is requesting a code from the app itself

Fyp.Perez 1 Reputation point

I recently deleted the Microsoft Authenticator app by accident, and why I downloaded it again and tried to sign in it is asking for a code from the app itself. I use an institutional account from university and now I can’t activate or even log in to 365 because it ask for the code from the app. Someone please help me.

    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.

    If no backup then you may need to get in touch with school admins to reset the two factor setup.

    Most likely yes unless someone has previously setup "sign in another way" option.
