Note: Junos Pulse and Tunnelblick have been retired. The VPN client used by CSU is Pulse Secure Connect Gateway. The Pulse Secure VPN is supported by Academic Computing & Network Services (ACNS), not ENS. These instructions are provided as a courtesy. If you have any issues with this tool please contact ACNS

Using DUO for Two-Factor Authentication

Beginning April 25, 2018, connecting to CSU using Pulse Secure and secure.colostate.edu will not only require you to log in with your eID and Password, but will also require you to verify your identify using a second factor device (your cell phone, a land line, or a hardware token).

  1. Download the Duo Mobile App to your smartphone. If you don’t have a smartphone or prefer not to use it for CSU business, you can skip this step.
  2. From your desktop or laptop computer, connect to the webpage https://authenticate.colostate.edu and review the documentation and FAQs – especially if you travel or work internationally, or if you use Pulse Secure.
  3. Click on the “Sign Up/Modify Devices” button and follow the instructions to register your second device. If you don’t plan to use a smartphone, register your CSU desk phone. Alternatively, hardware tokens that you can carry with you are available for purchase through RamTech. To learn more, visit ACNS token info page.
  4. Return to the ACNS DUO page and click on the “Test Your Account” button to make sure it all works.

Pulse Secure Connect SSL VPN

  • To initiate the client install double-click on the Pulse Secure package file. Click Continue then Install when asked and then accept the default settings during the rest of the installation.

  • When the installation is finished you should see a new icon in Applications named Pulse Secure.

  • In Applications, click on Pulse Secure. A Connections window should appear. Click on the “+” icon to open an add connection window.

  • In the add connection window keep UAC or SSL-VPN as the default type. You can name the connection whatever you want — for example, CSU. The Server URL for the secure gateway is https://secure.colostate.edu/2fa.

  • When you have finished entering the connection information click Add to save the connection, then click Connect. A login window should appear. Enter your CSU eID and password, enable the Save settings box, then click Connect. When a secure connection to the CSU network has been established you are now ready to start a remote desktop (RDP) client and connect to the Virtual Classroom.

  • IMPORTANT! Before Pulse can connect, it will need you to supply your second authentication factor that you setup using DUO. Once you have supplied this, Pulse will fully connect to the CSU network.
