08 Jun 2021

  The Computing Services Centre (CSC) deployed a new authentication system on 14 June 2021. The new system contains additional security features to protect your CityU Electronic ID (EID) and enhance the user experience by supporting single-sign-on to many CityU applications.  The extra security features include intelligent email notifications for login from new devices or locations and multi-factor authentication (MFA) support.

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