As the team administrator, you can force each team member to use 2-factor authentication (2FA).

When the value of force_2fa is true in this request, the member will be requested to activate 2FA by scanning a QR code next time they log in. To cancel enforcing them to use 2FA, change the value to false and send this request again.

This request is to be distinguished from the next request, because cancelling the enforcement doesn't necessarily Disable 2FA for A User in Team, which serves a different purpose.
