While Kagi supports multi-factor authentication via TOTP, there is no way for administrators of Teams to see whether their members are actually using it.
One way of making this possible would be to add the 2FA status (enabled/disabled) as a column in the Members table in the Teams settings. This shouldn't impact any existing workflows as it's purely additive.
I would foresee the administrators of some Team accounts periodically going to the Team members page and checking for users without 2FA enabled. They would then contact those users to prompt them to enable 2FA. Alternatively, checking the list might form part of an audit process.
Other services provide a variety of approaches. Often this is delegated to an identity provider (i.e. Microsoft/Google SSO) which enforces mandatory MFA, in which case it isn't needed in the service itself. In other cases mandatory MFA is supported by the service (GitLab/GitHub). Some services provide ways to get lists of users without 2FA enabled (Atlassian).
It feels like this would be a natural extension to the Members page: just another column.
