Azure MFA - New Phone, New Phone Number, Lost or Broken Phone

New Phone but same phone number

If you have acquired a new phone, but kept the same number, you should be able to authenticate using that phone number instead of using the Authenticator app that was synchronized to your old phone. When prompted for the Authenticator app, select the option 'I can't use my Microsoft Authenticator app right now' and then you will be presented with your other pre-configured authentication methods:

If you find that you don't have any other authentication methods, please reach out to the Help Desk for assistance. If you are attempting to update your Authenticator app to send notifications to your new phone, please refer to these instructions here
