A Zoom meeting that requires registration will allow participants to register with their e-mail, name, and to answer custom questions. This setup allows hosts to brand their invitation, estimate attendance, and to share the meeting link in a secure way. You can also generate meeting registration reports if you want to download a list of people that registered.
Note: Participants joining meetings with registration must use the Zoom desktop client or mobile app. They will not be able to join using the web client.
