To configure OpenVPN to connect to the Chemistry department:

  • Download this configuration file 
  • Download your personal credentials file - clicking this link should automatically download a file called credentials.txt. It is unique to you and you must not share it with others.
  • Copy the files into the OpenVPN config directory. For most users, you should copy the files to C:\Users\<your username>\OpenVPN\config\
    • If you use the Import File option, the imported configuraton file will instead be found in a sub-folder similar to C:\Users\<your username>\OpenVPN\config\chemistry-win10-token\ . In this case, you need to copy credentials.txt into that sub-folder.
    • Old versions of the software only supported storing the config files in a central location such as C:\Program Files\OpenVPN\config\ . If you have previously saved config files in that directory, you should delete them.


To connect to the department, find the 'OpenVPN GUI' start icon and doubleclick it. An icon of a white computer screen will appear in the system tray. Right click that icon and select 'connect'. A window will pop up showing logs as the connection is made. When the VPN is connected, the system tray icon will change to have a green line around the computer screen.
