Using DUO for Two-Factor Authentication

    Beginning April 25, 2018, connecting to CSU using Pulse Secure and 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 donít 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 and review the documentation and FAQs Ė 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 donít 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 DUO help
  4. Return to the ACNS DUO page and click on the "Test Your Account" button to make sure it all works.

    Pulse Secure SSL VPN

    These instructions are provided as a courtesy. The Pulse Secure VPN is supported by ACNS, not ENS. Please contact ACNS if you have any issues with this tool.

    1. Download the version for Windows 32bit/64bit here. Be sure to download the "Pulse Client manual installer VPN" client.
      (Not sure which operating system you have?)
    2. Double click on the file and install Pulse Secure. Just take all default settings during the installation.
    3. After the install finishes, you should see new icon in the lower right corner of your screen in the system tray.
      Pulse Secure tray icon
    4. Click on the Pulse icon and select "Open Pulse Secure". Click on the "+" icon.
      Pulse add connection
    5. In the next window, keep the default type as "UAC or SSL-VPN". For name you can put in what you want. Example: CSU
      The server URL is:
      Pulse add connection info

      Pulse connection added
      At this point, click the "Connect" button and login with your CSU Eid and password.
    7. In the next window, click the "Save settings" check box, then click the "Connect" button.
      Pulse save and connect
      You should get a green check showing you are connected.
      From here you are now ready to start up RDP client to connect to the Virtual Lab.
    8. 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.

    Now what? You may wish to map network drives or connect to a server.


    The Engineering SSL VPN does not work with the CSU wired network, but will work from the CSU wireless network, and from off-campus connections (wired or wireless).

    1. Make sure you have the latest Java Runtime Environment installed.
    2. Go to and log in with your CSU eName and ePassword.
    3. Allow Juniper Network Java applet to install (see note below if using Chrome or Opera).

    Once the applet installs, the web page will remain up. You can minimize the window or even close it and work as desired. There is a padlock icon in the System Tray. Double-clicking this will display the connection properties, including the IP address you've been assigned. Closing this window will disconnect the secure session.

    NOTE: If you are using Google Chrome or Opera as your browser you will need to click the start button for the "Network Connect" client application to start the vpn client.

    Now what? You may wish to map network drives or connect to a server.
