Two-Factor Authentication (2FA)
Two-Factor Authentication (2FA) is an important component in Information Security. 2FA adds an additional layer of security protection to the authentication process by making it harder for attackers to gain access to a person's online account. Please refer to the following section for more details about how 2FA can enhance the security of your account.
Lingnan University has implemented the 2FA solution on e-mails, MyLingnanPortal, VPN, Moodle, Qualtrics, Helpdesk System, Remote Desktop and Lingnan Scholars, and is mandatory for all staff and students in using these critical IT systems.
How it works?
The 2FA system requires an additional authentication layer in addition to your Lingnan username and password to ensure it is not any third party, but yourself, who accesses the services. This additional layer is usually a personal mobile device. By pairing your personal mobile device with a 2FA mobile app, the device will allow you to receive PUSH notifications for easy, one-tap authentication. You only need to respond to the push notification to gain access to the IT system you want.

[Important!!!] If you get an authentication request from Duo Mobile App that you weren't expecting, you must REJECT the request!
Is the service accessible from overseas?
The service is accessible worldwide. The DUO mobile app works well even after you have changed to use another SIM card (another phone number) during your travel. Please remember to carry your registered mobile phone/device as it is an important device to verify your identity in order to access applications supporting 2FA.
If your mobile device cannot access to the Internet, you can obtain a one-time ByPass Code from the Two-Factor Authentication (2FA) Self-Service . A ByPass Code will be sent to your registered personal mailbox.
