Although SM Admins can be locked down by IP Address would it be possible to allow 2FA to be setup for SM Admins? Granted, the most secure solution would be to lock down SM Admins by IP Address and use a VPN but there are situations where using a VPN isn't always practical or ideal. I'm suspecting that there is a reason this can't be done, such as the SM API?

Furthermore, it appears that you cannot lock down the Primary Admin by IP Address. You can toggle the option and set your IP Addresses, but the [SAVE] button is not available. Is this a bug or intentional?
