For any Two-Factor Authentication that will NOT allow use of your U2F Security Key, such as VPN and Adobe CC, OIT has the Duo Security One-Time Passcode tool.

Using the Tool

1. Using Google Chrome visit go.ncsu.edu/dc and sign in using your Unity credentials and U2F Security Key.
2. Click the Generate New Passcode button to generate a one-time passcode for use with Duo.
3. Use this code in your apps respective passcode field.

Note: Your Duo code will expire 10 minutes after it is created, used once, or when a new code is generated.
