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