• Confirm you are using the latest version of Zoom: Updating Zoom Version

• Refrain from publicly sharing a meeting link, otherwise anyone with the link can join your meeting.

• Avoid using your Personal Meeting ID (PMI) to host public events. Your PMI is basically one continuous meeting and you don’t want others crashing your personal virtual space after the session has concluded.

• Automatically generate a meeting ID and adding a password. Starting April 5, Zoom requires passwords if a user tries to enter a meeting using just the meeting ID instead of the meeting invite link. Adding a password: Meeting and Webinar Passwords

• Limit join before the host.  Effectively, the meeting will not start until the host was present.

• When scheduling a meeting, go to advanced options and uncheck join without host.

• Limit screen sharing. You do not want random people in your public event taking control of the screen and sharing unwanted content with the group. You can restrict this — before the meeting and during the meeting in the host control bar — so that you’re the only one who can screen-share. Managing participants in a meeting

• Lock the meeting.  Lock meetings once all expected participants have arrived. Locking a meeting ensures that no one else may join the meeting. Lock your virtual classroom

• Remove unwanted or disruptive participants: From the participants menu, you can hover over a participant’s name, and several options will appear, including remove. Click remove to remove someone from the meeting

• The Waiting Room feature: This allows the host to control when a participant joins the meeting. As the meeting host, you can admit attendees one by one or hold all attendees in the waiting room and admit them all at once. Enable the waiting room

• Locking chat feature: As the host, you can control who meeting or webinar participants are allowed to chat with. You can also disable the chat for all participants or disable private chat, so participants cannot send private messages. Lock down the chat
