Adding a Secondary Authentication Method
We recommend adding your phone number to your Microsoft account in the event you lose your phone or the app stops working. You would still be able to access your account through the backup method and re-add the Authenticator app to your phone. Otherwise, you would have to contact the Atlas Help Desk to reset your account which may take a while and setup the app again.
