Meeting hosts have control over who can come into their meetings and — at any time during a meeting — can mute, turn off video or remove any person.
You should start by going to the settings page to determine the defaults for all your meetings.
Setting options are:
Host video: Start with video on (on or off). The default is off which is a good idea. You can turn it on as soon as the meeting starts
Participant video on or off. The default is off which is a very good idea. You can turn it on for trusted participants
Audio type: Not really a security setting. It’s both computer and telephone by default, which is OK in most situations.
Join before host. Default is off. Prevents people from having a conversation before host joins. The off default is most secure
Use person meeting ID (PMI) when starting an instant meeting. The default is off but ON is more secure
Require a password when scheduling new meetings: On by default. A good way to keep uninvited guests away but you must remember to give everyone the password
Require a password for instant meetings. On by default. It will generate a random password that you must share with participants
Require a password for Personal Meeting ID (PMI). Generates a password to use if personal meeting ID is turned on. You can edit that random password.
Embed password in meeting link for one-click join. Meeting password will be encrypted and included in the join meeting link to allow participants to join with just one click without having to enter the password.
numeric password will participants joining by phone if your meeting has a password. For meeting with an alphanumeric password, a numeric version will be generated.
Mute participants upon entry. The default is off but by turning it on, no one can speak until you unmute them during the meeting
Other important security settings include:
Screen sharing. You can turn off the ability for particpants to share their screen, which prevents them from showing an inappropriate image or video
You can allow or not allow participants to rejoin if they’ve been removed by the host
You can control whether participants can put up a virtual background. They’re fun but one could contain an inappropriate image
You can require or not require a waiting room which prevents attendees from joining a meeting until a host admits them individually from the waiting room. If Waiting room is enabled, the option for attendees to join the meeting before the host arrives is automatically disabled.
Scheduling vs. (instant) Host a Meeting
There are two ways to conduct a meeting. You can click “host a meeting” from the upper right corner of your Zoom screen or you can Schedule a meeting.
If you select Host the meeting starts right away. You can change some settings and evict or silence participants later (see below), but it’s better to create rules in advance by scheduling the meeting.
If you select Schedule a meeting, you get a screen with a number of options. If you scroll down, you’ll see some of the security options that will override the ones that you set in the settings section for just this meeting. Settings include:
Meeting ID: A unique ID gives you greater protection so create your own ID #
Ability to require and set a meeting password to keep unwelcome visitors away
Whether the host or participants video is on or off. Turning off participant video by default prevents inappropriate images
Whether participants can joint before host, muting participants upon entry and enable waiting room, Waiting room is an important security option because it gives the host the power to let or not let people in. The host will be notified of who is in the waiting room.
The following in-meeting security capabilities are available to the meeting host:
- Meetings are encrypted by default
- Create Waiting Rooms for attendees
- Require host to be present before meeting starts
- Expel a participant or all participants
- Lock a meeting
- Screen share watermarks
- Audio signatures
- Enable/disable a participant or all participants to record
- Temporary pause screen-sharing when a new window is opened
- Password protect a meeting
- Only allow individuals with a given e-mail domain to join
