Thanks for pointing this out, Tony. The help has been updated with the new options.
Two-Step Authentication (or 2FA) is really where virtually all industries are headed these days as it provides an extra layer of security for users and helps protect their valuable data. As a result, we opted to make it available for all users, and then they have the ability to enable it if they want.
Domain administrators can make the use of Two-Step optional, or they can require its use, and system administrators have the ability to require it for all users of the SmarterMail server.
