Do you want to make sure your users are using Two Factor Authentication to keep their accounts secure?
Navigate to the Company Preferences page (under Company Settings). This page will have a setting that will allow you to require two factor authentication.
Once enabled, existing users will have seven days to enable two factor authentication. Once these seven days have elapsed, upon their next login they will see the following page prompting them to set up two factor authentication.
Going forward, newly added users will similarly have seven days from when they register their account to set up two factor authentication.
