One of the security options in Zoom is “Only authenticated users can join: Sign in to Zoom.” This feature requires that users be logged into Zoom, and is intended to keep uninvited guests out of your meeting. As this is an option that can be turned on or off, it is likely that some of your meetings will require authentication and others will not.
Here's how it looks when you select Schedule Meeting on your Zoom homepage:
If you try to log into a meeting and receive an error message, be sure to click on Sign In with SSO.
If you are not sure how you are logged in, click on your profile pic in the right corner and underneath that, it should have your email address listed as @tennessee.edu if you logged in with SSO.
If it doesn't, log out and log in again by clicking Sign In with SSO.
