How to use your domain name as OpenID

OpenID is an authentication system that allows you to connect in a secure manner, on several Web services using the same identifier. Do you know that you can use your blog (domain name) as address OpenID?  In fact, you only delegate your domain name service provider to OpenID.

Using your domain name to identify yourself on a site or service that supports OpenID, are often easier to remember than the original address. If you have a Google Account, you already have an OpenID address. The procedure for transfer of your domain name is simple. Just add two lines of code to your header.php file.

Here’s how you can use your domain name as OpenID:

1. Go to your Google profile. If you do not have an account, create one here.
2. Copy the URL of your Google profile.
3. Add the two lines of code in the head section of header.php of your theme.

<Link rel = "openid2.provider" href = "https: / / www.google.com/accounts/o8/ud?source=profiles"><Link rel = "openid2.local_id" href = "http://www.google.com/profiles/"profiles / your-name-of-profile">

On the second line of code, replace “profiles / your-name-of-profile” with the name of your Google profile.
Add the lines to header.php.

That’s it. The next time you access a site that supports OpenID, you can use the domain name of your blog as an identifier.
