Make your attendee names anonymous within the webinar room
As a webinar admin you can make it so that once an attendee enters the room, their names will remain anonymous to other registrants and presenters in the room. They'll still register and provide their names, so those will be in your reporting and analytics.
Enabling the Anonymity Setting
Get to the webinar dashboard and visit the Edit tab. Either Select Privacy on the left hand side of the page, or scroll down to the Privacy section of the Edit tab to find the Anonymity feature.
Once you select that box, a conditional field will appear. Here, enter an “alias” name that will replace all of your attendees’ names within the session. Enter the name of your choice in the Attendee Name field below. This is the alias that will replace attendees’ real names in the webinar room (you can also keep the default “Participant” as your attendee name in the room)
Be sure to Save Changes before leaving these settings.
When this is enabled, you'll find that attendees will be anonymized everywhere in the room, both in the engagement channel as well as the host control panel.
