Secure a Meeting or Class

It is crucial to secure your CMU Zoom meetings. Doing so ensures a safe and comfortable online learning and work environment. 

For that reason, all CMU Zoom meetings will be restricted by default in the following ways:

  • All meetings will require a passcode. This cannot be changed on an individual basis.
  • Only the host will be able to share content in meetings. This can be adjusted from within a meeting or class using Zoom's security options.
