Learn how to allow only those with Cal Poly accounts, specifically an @calpoly.edu email address, to enter your Zoom meeting.
When scheduling a meeting
Under Advanced Options, make sure Only authenticated users can join > Cal Poly Only is selected. If some of your attendees are not from Cal Poly, you will need to uncheck this setting for them to enter the meeting or require them to Sign in to Zoom.
From User Settings
You can also adjust this setting by going to your user settings and scrolling down to Only authenticated users can join meetings.
