When you get a new phone, try to keep your old phone intact long enough to get the Authenticator set up on the new one. This is the ideal situation.


  1. Begin the process by visiting https://mysignins.microsoft.com/security-info.
  2. Click "Add sign-in method" and choose "Microsoft Authenticator" from the list of choices.
    • Follow the instructions on the screen. You might recognize they are the same as the first time you set up the app on your outgoing phone. This is to set up the app on your new phone.
  3. When set up is complete, you will be returned to the webpage listed above. Now there will be more than one Microsoft Authenticator listed. Remove the one associated with the old phone. 


If your old phone is already wiped or no longer intact, please contact the Ambrose IT Department. Inform them of your phone replacement and the need for MFA to be re-registered because you don't have the old phone any longer.
