Q. RedID vs SDSUid
What's the difference between my RedID and my SDSUid?
Your RedID is a 9 digit number that begins with an 8 and was given to you when you first applied to the university. Your SDSUid is an @sdsu.edu email address and is your single identifier on campus that gives you access to many SDSU services including Blackboard, Canvas, Google G Suite, Microsoft Office, student email via Gmail, WebPortal, and secure WiFi using eduroam.
Blackboard and WebPortal allow login authentication with either your RedID or your SDSUid. Most other SDSU services require an SDSUid for login authentication.
