2FA

[untuned]

Would it be possible to include two factor authentication to logins, such as being able to enable it, or require it for certain users?

For example, a section in the system tab for enabling 2FA requirements for no one, admins, and everyone, and then another option to require it for specific users.

it would be really great

rather than re-inventing the wheel, integration with existing 2FA systems might be worth considering.

e.g., a 2FA login system may set server vars

$_SERVER['HTTP_REMOTE_GROUPS'] $_SERVER['HTTP_REMOTE_USER']

on successful login (1FA + 2FA), if enabled/configured, XBackBone could use the existence of those vars ...
