WARNING: Before You Change Your Phone or Phone Number
Getting a new phone is a happy occasion, but it may disconnect you from your authentication method with Azure.
If you used the Authenticator App as your method: Before you disconnect your old phone, remove the authenticator app from the phone. Microsoft offers documentation on how to do this without losing access to your security setup.
If you chose the Phone Option: You will still have to log into your security settings and update if you get a new phone number. If your number stays the same, no updates are necessary. See our documentation on choosing the phone as the MFA method.
Important: Microsoft strongly recommends that you add a secondary phone number or method to help prevent being locked out of your account if your primary phone is lost or stolen, or if you get a new phone and no longer have your original, primary phone number. Adding security questions/answers is highly recommended for all users.
For more information about using MFA, we recommend the Microsoft support site. There you will find sections that apply to you for the best results for your specific situation.
