Everyone seems to be talking about OpenID so why should I be any different. But hey this isn’t the only reason why I am writing about it. If OpenID catches up, the Internet will be converted to a single sign-on system. No longer will users haver to remember a hundred usernames and passwords, or keep the same credentials for all sites.
Basically, after you get your own OpenID you would lno longer have to fill in personal information to start using a site, rather you would click a logo similar to the one on your left to be taken to the OpenID provider. Here you will have to approve a request for your identity and return to the website that requested your identity in the first place. That’s how simple it is!
Integrate OpenID into your WordPress blog
Get the WordPress OpenID plugin and install it. From then on, visitors to your blog can quickly register login, and leave comments using their OpenID Identity.
