Zoom webinar

[MissD07]

Is there a setting  in zoom portal wherein  the Zoom webinar does not required registration but when joining, the attendees are required to enter their email address? There are attendees that when joining the webinar via browser or their personal app they login with their pet name or nicknames and sometimes doesn't input their email id. It is difficult to track in the report.

Some attendees doesn't have a zoom account so we don't consider the Authentication. Please advise
