VPN – Multi-factor Authentication

Using Multi-Factor Authentication (MFA) with Duke’s Virtual Private Network (VPN)

As of February 6, 2018, Duke has implemented a new security policy that requires all users of Duke’s VPN to use Multi-Factor Authentication when logging in. This easy-to-use reference guide will make your transition easier.


Before you begin to VPN: Setting up MFA

There are several options for Multi-Factor Authentication. You can use a smartphone, a tablet, a basic cellphone, an office phone, or a YubiKey (see Duke OIT link below for more information on the YubiKey).

  2. Choose your VPN using the dropdown arrow and click “
  3. Enter your NetID and NetID Password and click OK.

  • Enter your NetID and NetID Password and click OK.

  • You will then see a screen with an ‘MFA option field. Enter the number that corresponds with your preferred MFA option (using the device that you registered above).
  • Type ‘1’ to authenticate using the DUO app on your smart device.
  • Type ‘2’ to authenticate via phone call. You will receive a call and be prompted to press a number.
    Once you press this number, you will be connected to the VPN
  • Type ‘3’ to receive ten access codes via text message.

Each code can only be used once, and these codes are active for three days.

  • If you are using a YubiKey, place your cursor in the ‘MFA Option’ field and touch the gold button on the YubiKey.

The code will automatically be entered and you will be connected to the VPN.
