To sign into Zoom, it is required to use the Single Sign-On (SSO) method instead of the usual entering of an @illinois.edu email address and password. If you have signed in the normal way, you may have to delete that Zoom account through Zoom in order to avoid having conflicting Zoom accounts.
Note: This applies to every way you are signing into Zoom (e.g. Zoom.us website, Zoom application, joining a Zoom meeting, etc.).
If you have any questions or need assistance, please contact your ACES IT Pro. You can find your department's IT contact information here: https://techsupport.aces.illinois.edu/departmental-it-offices
