Agencies with Microsoft 365 need assistance with enabling, reset, or disabling Multi-Factor Authentication. MFA

If you're assigned the Authentication Administrator role, you can require users to reset their password, re-register for MFA, or revoke existing MFA sessions from their user object. To manage user settings, complete the following steps:

1. Sign in to the Microsoft Entra admin center as at least an Authentication Administrator.

2. Browse to Identity > Users > All users.

3. Choose the user you wish to perform an action on and select Authentication methods. At the top of the window, then choose one of the following options for the user:

   • Reset password resets the user's password and assigns a temporary password that must be changed on the next sign-in.
   • Require re-register MFA deactivates the user's hardware OATH tokens and deletes the following authentication methods from this user: phone numbers, Microsoft Authenticator apps and software OATH tokens. If needed, the user is requested to set up a new MFA authentication method the next time they sign in.
   • Revoke MFA sessions clears the user's remembered MFA sessions and requires them to perform MFA the next time it's required by the policy on the device. 

   Delete users' existing app passwords

   For users that have defined app passwords, administrators can also choose to delete these passwords, causing legacy authentication to fail in those applications. These actions may be necessary if you need to provide assistance to a user, or need to reset their authentication methods. Non-browser apps that were associated with these app passwords will stop working until a new app password is created.

   To delete a user's app passwords, complete the following steps:
