Restricted VPN (Non-CUHK Users)

Departments may request restricted VPN service for their collaborating partners, such as contractors or vendors, who are not CUHK staff or students. The requesting service solely serves projects that require non-CUHK units to provide remote support and maintenance to dedicated servers or machines in departments during a specific period of time. It is not for visiting guests or visitors use.

Beginning on Nov 2024, the use of 2-factor authentication (2FA) will be compulsory for every restricted VPN login, as governed by the Policy “Enabling 2FA on all Application Authentication”. The applicant department will be required to cover the Duo license fee to enable 2FA.
