Protect your Zoom meeting space and class sessions

Overview of Zoom security

Zoom's default settings for meetings allow anyone with the link to join a Zoom meeting. This low barrier of entry makes Zoom easy to use. However, with ease comes risk. People (or bots) with access to the link can join the meeting, including those who were not invited to the meeting but were able to gain access to the meeting URL or ID.

Zoom offers a number of security options that you can use to prevent unwelcome participants from joining your meeting or to limit their ability to share inappropriate content.

Several options are listed below, but it is not necessary to change all of these settings to protect the security of your meeting. Choose the options that will best address your specific concerns while still creating a convenient meeting space for you and your meeting participants. You can adjust settings while a meeting is in progress or when scheduling a meeting. Some security options are available only through the Zoom web portal at

Set security for all future meetings

The settings you configure will apply to all future meetings. These options are all available when you go to the web portal at and sign into Zoom. From the left navigation, select Settings. You may need to scroll down a bit to find some of these settings.

Adjust default settings for Join Before Host, Mute Participants Upon Entry, and meeting passwords to your preference. These options can be customized for individual meetings — the Settings options control what is set by default when scheduling a new meeting.

  • For Screen Sharing set Who can share? to Host Only.
  • Turn off Allow Removed Participant to Rejoin to ensure that if a participant is removed for inappropriate behavior, they cannot rejoin.
  • Turn off File Transfer or limit file types that can be shared to prevent sharing of inappropriate or virus-ridden files with other participants.

Set security for all cloud recordings

To secure the Zoom cloud recordings you create, navigate to your Zoom recording settings page. These options apply to all the Zoom recordings you create.

Restrict viewing of recordings to authenticated users

To restrict viewing, enable Only authenticated users can view cloud recordings from the Zoom recording settings page. When this setting is enabled, users must have a CWU ID to view the recording.

Set password protection for recordings

To set password protection, enable Require password to access shared cloud recordings from the Zoom recording settings page. When this setting is enabled, a random password will be generated that can be modified by the meeting host. This setting applies only to recordings generated after the setting is turned on.

To prevent people who can watch your Zoom cloud recordings to download them, follow these steps.

  1. Navigate to the Zoom recordings page
  2. Select Share
  3. Disable Viewers Can Download

Individual recordings

Set security for a single meeting while scheduling

When scheduling a meeting, you can configure security settings to:

  • Prevent participants from joining the meeting before a Host or Alternative Host arrives.
  • Require users to authenticate themselves
  • Require a meeting password

You can configure any or all of these options.

On the Schedule Meetings page/screen, under Meeting Options:

  • Clear Enable join before host to prevent participants from joining the meeting until a Host or Alternative Host arrives.
  • Check Only authenticated users can join to ensure that all participants are logged into CWU Zoom accounts.
  • Check Require meeting password to require password authentication when users enter the meeting. Passwords can be up to 10 characters. By default, the meeting invitation will include the password for participants, as well as a Join Meeting link that will enter the password automatically for invited participants. These settings can be changed in your User Settings in the Zoom web portal at

Set security for a single meeting during the meeting

During a meeting you can prevent participants from sharing their screen, keep participants muted, or remove participants.
