Restricting or allowing particular participant for any conference can be easily done through privacy features. Along with controlling entry and exit of attendees, these privacy settings ensure separation of various meetings taking place simultaneously.

As the name suggests, on-going session of a web conference can be locked at any moment with the number of users present. This restricts other participants from joining the meeting until host unlocks it.
