One login to rule them all

The big idea in OpenID is providing a decentralized single sign-on platform. Single sign-on is not a new notion however. Almost all the internet giants, like Yahoo, Google and MSN, use single sign-on across their properties to lower the threshold of accessing their services and to create a competitive advantage. The reason they do this is that signing up is actually a big barrier to entry for users of web apps. Users feel more comfortable when they don’t have to sign up to use an app – it’s much easier to give it a try and it’s less time-consuming to start using it.
