Issue
You want to be able to enforce 2FA (Two factor authentication) for everyone in a team.
Resolution
Unfortunately, we don't currently provide a way to enforce 2FA for every user in a team, so this will need to be managed collaboratively by both the individual users (who set up their own 2FA credentials) and the team Admins.
Enterprise users have a dashboard that allows them to see which users have 2FA enabled, which can be used to identify team members who do not have 2FA enabled.
Our documentation on how individual users can set up 2FA for their account can be found here - Enabling two-factor authentication.
