Blocking anonymous users, callers from joining webinar without registering

Hey, @Eddie_DOR.

It’s unfortunate that creating tightly-restricted Webinar access requires some specific settings which are that easy to figure out on your own. And more unfortunate that you can’t really guarantee rejection of everyone not authorized. 

You mentioned you don’t want attendees to have to register. Have you tried using Authentication Required?

While this doesn’t prevent anything from accessing the webinar, it does assure that everyone admitted is logged into a Zoom account – authentication-required doesn’t check that the user is logged into the registered account, just any account.  If there’s any disruption, however, flag the offender with Report to Zoom during the meeting. Follow up on the report using the Confirm Report process in this document:

Since the offender must be logged in, Zoom can teach them shown more easily that of authentication is turned off. 

Another possibility is to leverage a Zoom Events license. Zoom Events was built initially with very strict security processes. Over time, they’ve provided options to relax them, but you can go full -bore in a variety of ways, including creating group join links that will only allow logged on users with a specific domain name in their address to attend, or even based on presence in an uploaded email list; other guests can be invited, but must be logged into the ticketed access link to get in.
