myOpenID is an open source third party authentication tool allowing users to have one login across multiple websites. myOpenID is developed my JanRain.
Making life even better OpenID works with many websites where you may already have an identity. These include Facebook, MySpace, Google, Yahoo, AOL and Windows Live ID. Many sites will allow you to use your authentication information from one of these sites to login to their site.
JanRain eases the integration of OpenID with their RPX product. RPX allows websites to be up and running in an afternoon with OpenID. They recently launched a WordPress plugin for blogging sites. This site uses WordPress. I wonder if we’ll be getting OpenID 🙂
OpenID has launched a demo of the RPX product here. The plugin demonstrates the ease in which the RPX turnkey solution can be implemented.
OpenID now has over 35,000 sites using their product. These include high profile sites like PayPal, Plaxo, Sun and AOL.
I know that I use it with Yahoo as my identity provider for sites that accept them. I could use my myOpenID uthentication for all of them if I chose to do so. You should try it-it’s nice to able to use existing web identities instead of having to register at sites that you want to use.
