A live look at who has ClientManager open right now — not a login history, and not a full user directory.
Side menu → Site Admin → Current Users. Each row is a person with an active session right now — User, Connected Since, and Duration. Closing the browser tab removes someone from this list almost immediately.
The list is a snapshot, not a live feed — click Refresh to pull current sessions again. If someone has two browser tabs open, they'll show as two separate rows.
