By default, participants joining through the web client do not need to be signed in to a Zoom account, but the host can require authentication.

The web client can help users who are limited in what they can install or download, allowing them to use their web browser and join Zoom meetings without downloading the application. The Zoom web client allows joining a Zoom meeting or webinar in a web browser without downloading any plugins or software.
