Registering for an IT Account will give you access to Email, AirUC Wireless Internet, as well as other campus services.
Your eID identifies you as member of the University community or as a prospective student at UofC, giving you access to a variety of online services available to you through the myUofC portal.
You can access most services with your UCIT Account or your eID, but there are some services which require additional accounts. There are also circumstances where guests need access to only a particular service.
