OpenID

Fed up with creating new accounts for multiple websites, here comes OpenID for the rescue. It allows you to use an existing account to sign in to multiple websites without ‘sign up’. OpenID replaces the common login process that uses a login name and password for every website.

An OpenID is in the form of a unique URL (e.g., http:\\me.yahoo.com\testid), which is authenticated by the user’s OpenID provider. Some of the websites who supports, allows and provides OpenID are Yahoo, Google, ZOHO, Microsoft, AOL, PayPal, Verisign. The OpenID doesn’t rely on a central authority to authenticate the user. The OpenID protocol leaves the type of authentication to the provider, the authentication forms may include passwords and biometrics.

Let us create a OpenID with Yahoo!

1. Go to Yahoo OpenID website Yahoo! OpenID
2. Get Started, login with your Yahoo ID

4. To create custom identifier click on ‘Show customization Options‘. Check for available identifiers, Yahoo recomends not to use mail id as part of the openID as it may expose our mail id. click on ‘Save My Customization‘.
   

   Custom OpenID

Let us check how to use the OpenID.

1. Go to Live Journal, click on ‘Login with OpenID‘ in the login page to open the OpenID login page.
2. Enter your OpenID and click Login (I don’t have account in Live Journal)
3. This will forward it to Yahoo, where you need to login with Yahoo ID
4. Now you have logged into Live Journal using OpenID.

The major advantage of an OpenID is you need not create a new account for every website you visit, instead create an OpenID and use the same account to log into all websites you visit.
