If you need to delete your authenticator app from your security info methods

This works for all authenticator apps, not just the Microsoft Authenticator app. After you delete the app, you have to go into the authenticator app on your mobile device and delete the account.

Important: If you delete the authenticator app by mistake, there’s no way to undo it. You’ll have to add the authenticator app again, following the steps in the Set up the authenticator app section of this article.

To delete the authenticator app

  1. On the Security info page, select the Delete link next to the Authenticator app.

  1. Select Yes when asked to confirm to delete the authenticator app. After the authenticator app is deleted, it’s removed from your security info and it disappears from the Security info If the authenticator app is your default method, the default changes to another available method.

Change your default security info method

If you want the authenticator app to be the default method used when you sign-in to your work or school account using two-factor verification or for password reset requests, you can set it from the Security info page.

Note: If your default sign-in method is a text or call to your phone number, then the SMS code or voice call is sent automatically during multifactor authentication. As of June 2021, some apps will ask users to choose Text or Call first. This option prevents sending too many security codes for different apps. If your default sign-in method is the Microsoft Authenticator app (which Microsoft recommends), then the app notification is sent automatically.


To change your default security info method

  1. On the Security infopage, select Change next to the Default sign-in method
  2. Choose Microsoft Authenticator – notification from the list of available methods. If you’re not using the Microsoft Authenticator app, select the Authenticator app or hardware token
  1. Select Confirm. The default method used for sign-in changes to the Microsoft Authenticator app.
