How to Limit Your Meeting to Authenticated Users

You can restrict your meeting access to participants who have logged into their Stanford University Zoom account or have logged into Zoom with a Stanford-affiliated email address or another trusted email address.  If someone tries to join a meeting or webinar and isn't logged into Zoom, or isn't logged in with the specified email domain, they'll receive a message stating "This meeting is for authorized attendees only."

When guests join, you as the host will see their Stanford name in the Participant window. This setting prevents anyone from joining as an anonymous guest. Learn more about Authentication Profiles for meetings and webinars in the Zoom Help Center.

Stanford Zoom offers you a choice of three authentication profiles.  You can adjust the authentication profile on a meeting-by-meeting basis. Look closely at each authentication profile to select the one that meets your needs.
