    Hi, someone with admin permissions needs to do the following for this user:

    • Sign in to the Azure portal with the tenant Global Administrator account.
    • Navigate to Azure Active Directory > Users > All users > Choose the user you wish to perform an action on > select Authentication methods > Require Re-register MFA.
    • Once this is done, the next time the user signs in, he/she will be requested to set up a new MFA authentication method.
