When we travel site to site we might see OpenID system which allow us to log into the site without any paper work. We don’t need to create another password. Its really good way to minimize the list of user name and password.

Many of us really hate to create another user name and password. Your visitor is not difference. It is good idea to add OpenID authentication system for those lazy visitors. Wordpress is the most widely use blog software and I will tell you how to add OpenID system on it.

Just download any of the following plugin and add it using your ‘add new‘ feature located under ‘Plugins‘ section on your ‘Dashboard‘ and active it.

1. RPX : The RPX wordpress plugin let’s you use OpenID, Facebook, MySpace, Google, Yahoo!, and Windows Live ID authentication on your blog.

2. OpenID : Allows WordPress to provide and consumer OpenIDs for authentication of users and comments.

3. VidoopConnect : It makes it easier than ever to sign up and login to your site by letting your visitors reuse their existing accounts from sites like Google, Yahoo, AOL, Facebook and MySpace, or any other OpenID provider.

4. Alternate OpenID : Allow OpenID based commenters to add their thoughts via comments on your WordPress blog.
