YubiKey Authentication Module
YubiKey authentication modules are developed to add YubiKey two-factor authentication to server-side applications.
The YubiKey Authentication Module can validate the OTP against either its own Validation Server or against the Yubico Online Validation Service.
Organizations can decide which model works best for their application. The main benefit with your own server is that you are in full control over all AES keys programmed into the YubiKeys.
The main benefit of using the Yubico online Validation Service is that the YubiKeys are already ready to use with the Online Validation Service out of the box (no additional handling needed). It also enables users that already have a YubiKey to sign up for your service.
