New CityU Authentication System with a New Look
For Staff & Students
08 Jun 2021

  We are glad to inform you that a new authentication system will be launched on 14 June 2021. The new authentication system contains additional security features to protect your CityU Electronic ID (EID) and facilitates single-sign-on to many CityU applications.  The extra security features include intelligent email notifications for login from new devices or locations as well as multi-factor authentication (MFA) support.

After the launch, when you log in, you will be prompted with a new login screen.  As usual, please enter your “EID” and “password” to access the target system.
