Control Center lists the users for your organization. Users with additional permissions or roles have icons next to their username: system administrators (), security users (), VoIP users (), users with two-factor authentication ().
Search for the user by doing one of the following:
Scroll through the list of users. If you have more than 20 users, use the arrows at the bottom of the page to navigate between pages.
Start typing part of the user's first name, last name, or username in the Search field. (Control Center filters the user list as you type.)
When you find the user, click the icon on the row for the user.
In the window that appears, click OK to confirm you want to delete the user.
