To join a Zoom meeting as a participant, as long as the meeting host has changed a few settings to allow guest participants, you don’t need to create an account with Zoom. You can join a meeting by opening a link in your browser. The host must set Authentication Profiles to be disabled, or create specific authentication exceptions that allow guests to join. They must also disable the Only Authenticated Users Can Join from Web Client setting. Finally, they should have a “Join From Your Browser” link enabled in their settings.
