Zoom: Tips for keeping meetings secure



Intended for:

Zoom meeting hosts.


Scenario/Use case:

This article contains instructions on how to keep Zoom meetings secure.




Posting meeting IDs and passwords on public websites:

You MUST NOT post Zoom meeting IDs, links or passwords on any public website (including in Indico and DocDB).


Preventing participants from screen sharing:

By default for all meetings, only the host, co-host or alternative hosts are allowed to share their screens. Hosts, co-hosts or alternative hosts may override this setting at the start of or during a meeting. You can learn about the differences between roles in this article from Zoom: (Note: Not all features listed in this article are available for Fermilab account holders.)


Setting passwords to prevent unwanted participants from joining:

As of July 18, by default, all meetings require a password to join including meetings where participants dial in by phone.

For those who send email/calendar invitations with the Zoom meeting link, an encrypted password will be embedded in the link, so participants do not need to type the password. (The link with the encrypted password will look something like this:

REMINDER: The embedded link or password MUST NOT be posted on a public webpage.

Per meeting, you can assign a password, up to 10 numerals, letters or a mix of both. Here’s what the password field looks like when scheduling a new meeting from the Zoom client:

For phone participants, the phone number password will be a numeric-only, Zoom-generated password that cannot be changed. The Zoom-generated invite will look something like this. NOTE: If you had scheduled a meeting prior to July 18, 2020, and the meeting will have phone participants, you will have to send out an updated meeting invitation which will include the dial-in password.
