What is OpenID?
OpenID is an open, decentralized, open-source framework for user-centric digital identity.
Think about all the accounts you have online: blogs, wikis, to-do lists, photo galleries. The list is endless. Even simple tasks such as leaving comments on someone else’s blog may require you to register an account with that particular blogging system. This leaves you, as an end user, to set up and manage numerous accounts on each of these sites. With OpenID, rather than managing all these disparate accounts individually, users can manage their identity in one place via an authentication server.
