Re-register MFA not forcing a user to change their authentication method, still defaulting to old method when logging in.

Having some issues with the MFA re-register button in the Azure AD admin portal where the button is not doing what it should. This has happened recently for a couple users. I was originally thinking it was something that needed to be synched, but after 12 or so hours of it still not working I believe that is no longer the case. Is there another way to re-require MFA within the portal itself?

    Hi @Ethan Matthews • Thank you for reaching out.

    There is no other way to re-require MFA within the portal but you can use PowerShell cmdlet for this purpose, as mentioned below:

    1. Run Install-Module MSOnline from elevated PowerShell (run as administrator) to install the required module.
    2. Run Connect-Msolservice and sign-in using Global Administrator/Privileged Authentication Administrator account.
    3. Run Set-MsolUser -UserPrincipalName username@your_tenant.onmicrosoft.com -StrongAuthenticationMethods @() to require given user to re-register for MFA.
