Using your UGent login name (username) and UGent password you can log in to a large number of UGent applications (Minerva, e-mail, Athena, etc.) These applications use a central authentication service: passwords are not stored in the application.
CAS is the central authentication service for UGent. On the CAS (Centrale Authentication Service): introduction-page you find the answers to questions as "What is CAS?/ What is Central Authentication?", "How long do I remain logged on?", "How do I log out?".
UGent pursues Single Sign-On wherever possible. As a user you need to log in only once per session.
UGent also offers Federated Single Sign-On: you can use your login name and password to log in to (web)applications at trusted organisations.
Usernames are lower-case, check if the caps lock key has been switched off.
The password is case-sensitive: check if the caps lock key has been switched off.
