What is openID? For the lengthy explanation check out the wikipedia definition here or a simpler one below:

"OpenID is a decentralized single sign-on system. Using OpenID-enabled sites, web users do not need remember traditional authentication tokens such as username and password. Instead, they only need to be previously registered on a website with an OpenID "identity provider", sometimes called an i-broker. Since OpenID is decentralized, any website can employ OpenID software as a way for users to sign in; OpenID solves the problem without relying on any centralized website to confirm digital identity."
