  • Meetings can be locked.

Cloud Recording Storage: Cloud Recordings are processed and stored in Zoom’s cloud after the meeting has ended; these recordings can be password-protected or available only to people in your organization. Cloud recording and audio transcripts will be encrypted when an administrator enables cloud recordings and audio transcripts for a meeting.
At the bottom of your Zoom window, click the Security icon. Click the Lock Meeting button in the pop-up. Set up your meeting with a meeting ID and a passcode when scheduling it. Attendees can be informed privately of these details.

Use Zoom security features during a meeting

You are invited to join your Zoom meeting. When you are in the meeting control, click the Security icon, then you can enable waiting rooms, lock meetings, remove participants, or any other function you like.
