Enable 2FA on user to login to Azure portal
I found that if the user in the directory was added to the Azure directory via ARM "or Classic (if not tick for the option "Enable Multi-Factor Authentication" ) , we will not be allow to enable 2FA to the user account in classic portal.
I hope there is a way to enable this option "Enable Multi-Factor Authentication" for existing users especially the initial account user for the subscription which hold the Global Admin role.
Have been searching for solution to enable the 2FA for existing user in directory, but no avail...
Am surprise also that only Classic mode have the option and not in the ARM mode.
