OpenID Delegate Plugin
OpenID Delegate WordPress plugin will add OpenID delegation abilities to your blog, thus allowing you to sign in to various OpenID supported sites using your blog’s URL.
In order for the plugin to work you must have an account on an OpenID server. If you don’t want to (or don’t know how to) run your own OpenID server you can register in a free OpenID server such as myOpenID or if you already have an account in one of the sites listed here (note: not all of them are OpenID providers, some are only consumers), you can use them to delegate the request directly to the servers there.
