My Domain, My OpenID
So.. you have a domain, like example.com, then you have an account on OpenID provider, like example.myopenid.com. You make a blog on your domain and use your OpenID if you connected with web that support it. Now the question is, why don’t you use your domain as your OpenID?. Don’t think it will be difficult, it is absolutely very simple.
One thing that you have to do to make your own domain as your OpenID is add a little html meta tag on your website.
<html>
<head>
<title>Example Website</title>
<link rel="openid.server" href="http://www.myopenid.com/server">
<link rel="openid.delegate" href="http://example.myopenid.com/">
</head>
</html>
Abracadabra.. now you can using your own domain as your OpenID.
Ok.. I am just kidding about abracadabra.. actually there is no magic behind this process. Technically, this technique is called ‘OpenID Delegation’, a technique to make your domain delegate OpenID request to the OpenID provider.
But wait a minute.. what kind of animal OpenID is?.. Oh.. damn.. I forgot to explain it to you?!. Basically OpenID is a way to identify yourself to websites using a URL rather than username and password. So you don’t have to remember username and password for every single site. For websites that already support openID you can use your OpenID url and you will be able to register or login easily. Reading more detail on OpenID official website and watching screencast from by Simon Willison will give you good understanding about OpenID.
If you don’t have any OpenID account yet, you can sign up for OpenID. There are a lot of OpenID provider out there, maybe you need OpenID comparison to decide the most suitable provider for you.
