All existing Unikey users please follow these steps if you see the registration screen during login.

This is a once off process for Unikey users to overcome needing to re register.


  1. At login page, new or existing users to use Unikey and Password to login.

2. At the next page on the bottom right hand side, click on ‘Register’


3. You’ll then get an error message displayed


4. After this appears, return to xnat.sydney.edu.au, login using your unikey and you will be granted access this time. When you come to login every time after that it will be as per normal.
