What is OpenID?
OpenID is a single sign-on system, which allows internet users to log on to many different web sites using a single digital identity, eliminating the need for a different user name and password for each site. OpenID is a decentralized, free and open standard that lets users control the amount of personal information they provide.
Using OpenID-enabled sites, web users do not need to remember traditional authentication tokens such as username and password. Instead, they only need to be registered with any OpenID “identity provider” (IdP). Since OpenID is decentralized, any website can use OpenID as a way for users to sign in; OpenID does not require a centralized authority to confirm a user’s digital identity.
OpenID is increasingly gaining adoption among large sites, with organizations like AOL, Google, IBM, Microsoft, Orange, Verisign, Yandex and Yahoo acting as providers.In addition, integrated OpenID support has been made a high priority in Firefox 3 and OpenID can be used with Windows CardSpace.

Recently Officially blogger enabled OpenID for bloggers. And it’s really cool and a new steps on blogger.com and maximum people long time looking for this features and people now a days enjoying
From Bloggerindraft “
As we hinted before, we’ve been working on making Blogger an OpenID provider. With our latest Blogger in Draft release, we’ve done just that. You can now use your blog’s URL as an OpenID URL on any website that accepts OpenID 1.1 authentication.
To enable OpenID for your blogs, just edit your profile on
draft.blogger.com and enable the checkbox which says Enable OpenID for Blogs and you are all set!
After checking this box, you can use the URL of any of the blogs you are an admin of as an OpenID identity. When you use it to log in to another site, you will be taken back to Blogger where you can confirm that Blogger can tell the site that you own the domain.
You can find more information about OpenID and how it works at OpenID.net.
We hope you’ll try out using your blog as your OpenID identity around the web. Let us know how it goes in the comments! If you’re looking for things to do, take a look at MyOpenID’s OpenID Site Directory for OpenID-enabled sites.
Since this feature is still in draft, there are a few caveats:
- We currently do not support OpenID for blogs that aren’t hosted on Blog*Spot or a custom domain, such as FTP blogs. However, the OpenID web site has a help page that explains how to workaround this limitation by delegating your FTP blog to a Blogger-hosted blog.
- If you say “Yes, Always” to trust an OpenID site forever, you cannot now delete that trust. We will add this feature soon.
