Two-factor authentication (2FA) is a security system that requires two distinct forms of identification in order to access something. In regards to emails, centrally enforced 2FA means that in order for your team to login to their emails, they will need to use a secondary source of authentication to prove it is actually them and not a hacker. Commonly this is a text message sent to the team member's phone which they then enter into the email system to gain access. 2FA may also be called "Multi Factor Authentication" or "Dual Factor Authentication"
