Our WordPress installation here at International-Anarchy.com supports OpenID authentication. What does that mean for you? Well if you have an OpenID and wish to make a comment on our website, all you have to do is provide your OpenID URL when commenting to pass on your user information. For Team Members given access to the WordPress backend, you can now use an OpenID to login to the website, simplifying and speeding up authentication.
You can look into the OpenID project here: OpenID.net
Read more about OpenID: OpenID on Wikipedia
And finally, you can get and OpenID for use here: MyOpenID
In short the best way to describe OpenID is this:
OpenID is a free and easy way to use a single digital identity across the Internet. With one OpenID you can login to all your favorite websites and forget about online paperwork. Now, you get to choose the login that’s right for you. Get an OpenID today!
I am also looking into a few different options to support OpenID on our forums too, so stay tuned for that in the near future.
