The One-Time Password (OTP) system is a two-factor authentication system. Two-factor authentication means that you are authenticated using something you have and something you know. The LLNL OTP system uses a token code from an OTP token as something you have and your personal identification number (PIN) as something you know.

OTP Tokens

When you use your OTP Token to authenticate, your password is your (PIN + token-code).

The token code is the 6 digits displayed by the OTP Token. It changes every 30 seconds. The password, also known as passcode, is a single string without spaces. For example, the OTP Token above is displaying a token code of "032848". If your PIN was "abc12def", you would then enter "abc12def032848" as your password.
