OpenID

Now a days, we see OpenID on so many websites. Wanted to know what this concept was about.

In simple terms, OpenID is a Universal ID (specifically a URL) which once created, can be used on an OpenID complaint website for a specific activity. For eg. on Blogger (OpenID compliant website), one can comment (specific activity) using an OpenID. One need not create a separate OpenID if one already has a Gmail id (or Google Accounts ID), Yahoo id, a blog on Blogger, etc. Best part about OpenID is that it is not dependent on any single OpenID provider. One can switch to any OpenID provider as one wishes, without monopoly of any specific company. It is an open standard with decentralized server.

So, next thing to know is which all are the OpenID providers. The list is here as well as here.
