But a new web service has been under development for some time now called OpenID and I have been sitting patiently waiting for it to mature. Well that moment I think is here as on January 30th Yahoo will support OpenID which means that if you already have a Yahoo ID and password you can use it to logon to any OpenID enabled website. This is what Yahoo says:
Once you enable your Yahoo! account for OpenID access, you can simply tell any OpenID enabled web site that you are a Yahoo! user. You will be sent to Yahoo! to verify your Yahoo! ID and password and then signed in to the web site. Its that easy!And its not only Yahoo that supports OpenID. Other service providers also provide support such as Technorati and AOL.
