You can manage the status of each of your event users and set whether they are active, deactivated, or deleted. Deactivating or deleting a user will remove the user's access to the event.
To delete or deactivate a user, log in to Events Builder and select your event. Select Admin> Users in the left navigation menu, use the search bar to find the user, click the ellipses icon, and select either Deactivate User or Delete.
Deactivated users will be moved from the Active Users tab (a) to the InActive Users tab (b) on the User Management page, and Deleted users will be moved to the Deleted Users tab (b).
