If you are an Administrator and want to ensure that all the users in your portal have enabled two-factor authentication you can contact Admincontrol Support with details about the portal you wish to enable it on.
Any user who has two-factor authentication enabled by an Administrator in one of their portals will get two-factor authentication enabled in all their portals by default. This is to make sure that all the portals a user is a member of have the same high level of security connected to them.
Please note that if an Administrator has not enabled two-factor authentication for you, you can enable this yourself in the Settings under Password and Electronic ID. This setting can also be turned off if none of the other portals you are a member of has two-factor authentication required by an Administrator.
