YubiRADIUS No Longer Works With YubiCloud v1 Protocol

As Yubico announced a few months ago, Yubico is no longer supporting the YubiCloud v1 protocol. This took full effect on February 4 of this year.

As such, any YubiRADIUS systems utilizing the YubiCloud will no longer validate YubiKey OTPs as before.

Fortunately, for such YubiRADIUS deployments, GreenRADIUS can be used as an easy replacement. The same team that built YubiRADIUS is now maintaining and adding features to GreenRADIUS. We even have an easy-to-use YubiRADIUS-to-GreenRADIUS migration tool.
