You can sign up with any of the providers for OpenID URL. URL will be hosted on the provider’s domain (for example yourid.myopenid.com). It can be an issue, if you are not happy with your provider or if your provider goes down and you want to switch to another provider. To avoid the problem, You can use your own custom domain name such as your blog URL or website (http://www.yourdomain.com/) for Open id. The technique is called delegation.
Before using the technique, check your provider website for any other method for using your own custom URL. For example, if you are using Blogger to host your blog and forward it to custom domain name, you are automatically setup to use the feature. Simply, use your Custom Blog URL as openid and you will be forwarded to Blogger account.
If you are using MyOpenid.com as provider, simply copy following 2 lines in the head section (Just before </head> tag) of your blog or website html to use OpenID delegation.
<link rel=”openid.server” href=”http://www.myopenid.com/server”/>
<link rel=”openid.delegate” href=”http://YourMyOpenid.myopenid.com/”/>
Then use your blog or website URL (http://www.yourdomain.com/) as openID and you will be forwarded to Myopenid.com for authentication. If you are using any other provider, simply change the server name and openid URL accordingly.
