When a user loses or replaces a mobile device or can’t use the Authenticator app, they can’t sign in to Microsoft 365. The admin has to re-register the user’s Multi-factor Authentification (MFA). The MFA settings for this user will be removed, and the user needs to set up the MFA options on the next login. In this article, you will learn how to reset MFA for a Microsoft 365 user in Microsoft Entra ID.
Before the next step, you need admin permissions to reset MFA settings.
In our example, we want to reset the MFA settings for the user Hannah Duncan.
Time needed: 10 minutes
Follow the steps below to reset MFA for a user in Microsoft Entra ID:
