Zoom Hosts can restrict meetings so that only authenticated (signed in) users that are signed into the Zoom App can get into meetings.  Restricting meetings to only authenticated who are signed in with SSO has benefits.  On the one hand, it allows hosts to successfully implement pre-assigned breakout rooms and prevent Zoom Bombing.  It also allows hosts to get accurate attendee reports.  However, on the other hand, this can create a barrier into the meeting if the attendee is not signed in properly with their Stony Brook Single Sign On (SSO) credentials.  This article will show you how to migate that barrier by implementing and customizing the  Waiting room to capture attendees who are not signed in and then provide them instructions on how to sign into the Zoom App with SSO correctly.  It is important to note that when users are signed into the Zoom App with their Stony Brook credentials  they will generally be signed in automatically every day until they sign out or if their computer receives a major update.

*It is a good idea to communicate to your attendees ahead of time if you require them to authenticate into the Zoom App for your meetings.  You can send them this link which will instruct them on signing into the Zoom App with SSO.
