OpenID is a single login that you can use across many websites on the internet. With OpenID, you no longer need to create a username/password when registering on a new website. You can simply use your existing OpenID.

Using OpenID

Using an OpenID to login to a website is similar to the notion of showing your driver's license at the box office when picking up tickets or showing your driver's license at the airport security to prove your identity. OpenID is a single digital identity that you own. You present it when logging in to a website or at a blog post when submitting a comment.

You can only use OpenID on Websites which accept OpenID. Look for the OpenID symbol or text like "Login using an OpenID" as shown in the image on the right.
How does OpenID work?

1. You get an OpenID with one of the providers (more on this in the next section). Your OpenID is a short URL, for example mine is http://www.vineetmanohar.com
2. You go to a website which accepts OpenID, for example, Stack Overflow
3. You enter your OpenID and hit Login
4. Your are redirected back to your OpenID provider's website. You login there using your login/password that you setup in step 1. After logging in, you are automatically redirected back to website X where you came from.
5. When you land on website X, you should be logged in.
6. You can repeat the same procedure for website Y. Note that login/password only occurs on your OpenID provider's website, so you only need to remember one login/password.
