Resources to host an independent YubiKey validation server, instead of YubiCloud
We provide the YubiKey OTP Validation server for developers looking to integrate the YubiKey OTP Validation with an existing web site or service. An example implementation of the Yubico Validation server may be observed in the YubiRADIUS Virtual Application, where it is used to store and track the YubiKeys and YubiKey OTPs.

Please note: Third-Party Servers are not written by Yubico.
Support for both OATH and YubiKey:
