To improve security at the University, we are introducing Duo Security, a two-factor authentication system. Duo will work in China, you should be aware of the following guidance.
If you are in China you can download the Duo Mobile App direct from the Duo website.
If you are travelling to China, download the app before you arrive in China as the Google Play store is not available in China.
If you cannot use the push notification, you can use the app to generate a passcode to authenticate rather than using the push notification.
Yes, SMS messages sent from Duo should work in China.
