Details:
One-time email passcodes provide an easy way for tenant administrators and event organizers to verify anonymous, external presenters invited to their events. Anonymous external presenters will be shown with a "Verified" tag once completing the process. Based on admin settings, the event organizer will also have a set of options available to them that applies to all external presenters, providing the ability to control who is admitted to the meeting or allowing uninvited users with the link to be admitted from the lobby.
