Unified Identity Authentication (CAS / SSO)
Zhejiang University's unified identity authentication platform, a Central Authentication Service (CAS) single sign-on login used to access campus systems. It supports username/password, QR-code scanning, and third-party login (DingTalk, QQ, WeChat, Azure/Microsoft for international campus). This is an internal SSO gateway, not a self-service public API; no public developer documentation is published.
