This article shows how users can use a YubiKey when authenticating with the RADIUS agent in an "Accept password and security token in the same login request" flow.

• YubiKey
• RADIUS
• Multi-Factor Authentication (MFA)

Please follow these steps:

1. Plug in the YubiKey.
2. Go to the VPN login window (or NTRADPING to test this with RADIUS).
3. Type the username.
4. Type the password followed by a comma.
5. Let the cursor (pointer) after the comma.
6. Touch the gold contact on the YubiKey device, and an OTP token will be generated after the comma in the password field.
