Securing Your Virtual Classroom/Meeting

Emerson College aims to create an environment where classes and college business can be conducted accessibly and securely.

Keep your Zoom URL secure

Unfortunately, malicious attackers scrub the Internet for publicly posted Zoom URLs. Often, Zoom URLs include the passcode as part of the URL, bypassing the security of the passcode entirely. For this reason, we highly recommend that you never post Zoom URLs to open Internet sites such as Twitter or public facing Facebook pages. For EmConnect, it is safe to post if the page requires that users log in, but not if it is open to the public Internet.


By default, all newly hosted Emerson meetings require authentication, which means attendees need to log into Zoom (either the desktop client or the web interface) before joining. To configure this setting, log into, go to the Meetings tab on the left, and then choose Schedule a Meeting on the right. Under Security, you'll see a checkbox for "Require authentication to join", and you can remove this or make it more strict by restricting authentication to only attendees.

We highly recommend requiring this feature in all meetings, even if there will be external attendees, as it prevents anonymous participants outright. Anonymous participants are almost always the perpetrators of harassment on Zoom. For additional security for Emerson-only meetings, change the setting to only allow Emerson Zoom users.


When you schedule a new Zoom meeting, whether from, through, or via Google calendar, Zoom will automatically generate a unique passcode for the session. You can customize the passcode, if you'd like.

The meeting invite link generated by Zoom will automatically include the passcode. Participants will not need to know the passcode explicitly unless they are joining only via the Meeting ID (the 9-digit unique meeting identifier) or using the browser-based version of Zoom.

However, we do still advise sharing the full meeting information (the link, meeting ID, and passcode) with your participants to ensure everyone can join without an issue.

Where can I find the link, meeting ID, and passcode?

Sign in to, click on Meetings, and click on the name of your meeting under Upcoming. In Canvas, you can see the same thing by going to the Zoom tab in your course.

What about students joining Zoom meetings via Canvas?

Students will not be required to enter the passcode when joining a Zoom meeting via the Zoom desktop or mobile app, including those in Canvas. Students will only be prompted for the passcode if they join by typing in the Meeting ID or via the browser-based version of Zoom.

To be completely safe, faculty should post the passcode in a location accessible to students to ensure they will be able to join the meeting in all circumstances.

If the passcode is included in the link, how does that make my meeting more secure?

The passcode protects against outside attacks from intruders who guess—or use an app to select—a random Meeting ID (the 9-digit meeting identifier) and then attempt to join the meeting unexpectedly. Potential intruders would not be able to enter a meeting this way without also knowing the passcode.

This measure, however, will not prevent invited guests from intentionally sharing the link or meeting information with others.

What about my Personal Meeting link?

Your customizable Personal Link will prompt attendees for a meeting passcode when joining. To avoid this, be sure to use your Personal Meeting ID link, which can be found by navigating to your Personal Meeting ID in your Profile at (click Show next to the link to view it in full).

If you are currently using your Personal Meeting room for class, be sure that you are sending your students the full Personal Meeting ID link, which includes the passcode, in advance of your sessions.

Can I decide to turn off the passcode for my meetings?

No. In alignment with Zoom's recommendations and the assessments of our own information security team, all Emerson Zoom meetings must have passcodes.

My Zoom class/meeting was interrupted. What should I do?

Please report incidents of unwanted virtual meeting disruptions to us at, and to the Emerson College Police Department at 617-824-8555. If you have been impacted by identity-based harm, you can seek out support from Intercultural Student Affairs or share your experience anonymously with the Social Justice Center or at

Read on for a list of recommended Zoom features for managing meetings that can help you safely share your Zoom class or meeting and avoid unwanted interruptions. These are listed in the order of easiest to implement to hardest:

  • Share Links Safely
    • Be aware that sharing your Zoom meeting info publicly or on social media means anyone can join. Be careful about where you post your link.
    • When posting your virtual events on EmConnect, make sure you've set your Event Visibility to Students & Staff at EmConnect. This ensures it will only be visible to people who have logged into EmConnect.
  • Mute all participants
    • This is a good practice for any meeting—muting participants by default helps prevent echo and other audio issues.
  • Remove participants from a session
    • As the meeting host, you can boot someone out if they're being disruptive or should not be there in the first place.
    • Warning: If you remove a participant from a meeting, they will not be able to rejoin that meeting with the same email address. Only use the Remove function if you want to ban the participant from your meeting.
  • Lock a meeting in progress
    • If you have confirmed that all participants have successfully joined, you could lock the meeting so that no further participants can jump in. This could also be useful if you see a disruptor join. You can remove them and lock the session to prevent them from rejoining.
  • Enable Waiting Room 
    • This feature requires the meeting host to allow each participant to join the session individually through the Participant's Pane.
    • Warning: this level of multitasking can be tricky once you've started leading a session. You'll have to remember to check the participants list frequently for any late-comers!
  • Add a trusted student or colleague as a co-host
    • They can help you with participant moderation: admitting people from the waiting room, muting participant microphones and audio, and removing participants.
  • Host your meeting using Zoom at Emerson (logged in with your Emerson account, at, not with a personal account, which won't take advantage of our security management.

How can I secure my Zoom cloud recordings?

Cloud recordings can be downloaded by the host, or shared via a link—when the host clicks the Share button next to a cloud recording, they will see options to:

  • share the video publicly (not secure, anyone with the link can view)
  • share with authorized Emerson Zoom users only (recommended for classes)
  • passcode-protect the recording (recommended) 
  • prevent viewers from downloading
  • allow others to request access to view the recording via registration
