For a seamless experience, it's important to manage how anonymous participants join meetings and webinars in your org. Anonymous participants include users who join a Teams meeting without signing in, via the Teams web app, or through external meeting platforms.

If your organizers allow anonymous users to bypass the lobby, web bots might join and disrupt their meetings and webinars. As an admin, you can require human verification checks for anonymous users to join meetings in your org. Requiring a CAPTCHA challenge can prevent unwanted web-based bots from joining, recording, and causing disturbances in meetings and webinars.

Manage verification checks for meetings and webinars in your org

You can use the Teams admin center or PowerShell manage verification checks for meetings and webinars in your org. You could also use a sensitivity label in Purview or a meeting template to require verification checks. To use meeting templates and sensitivity labels, you must have a Teams Premium license.
