Organization users are the individuals who have administrator access to an organization. Users have access to all the organization's events, as well as to all the functions of the organization space: create new events, access the list of community members, check the messages service, and much more.
Add a user
To add a new user, go to Settings > Users and click on Add a user. Enter the user's e-mail address to send him/her an invitation to join your organization: the user must click on the link received by e-mail and accept the invitation.

Require two-factor authentication (2FA)
Two-factor authentication (2FA) strengthens the security of your account by requiring two methods of identification: your usual password and an additional code that you obtain via a dedicated application.
To secure access to your organization space and events, you can make it compulsory for users of your organization and events to activate 2FA in order to log in. This will only impact the users (those with access to event management functionalities) and not the team members of your events.
To require two-factor authentication in your organization, go to Settings > Users in your organization space and click on Require two-factor authentication.
