Single Sign-On/SSO for WordPress

Single Sign-On for WordPress is a professional extension that automatically signs users in as they browse between multiple and independent WordPress blogs in your network. Take away the need for your users to re-enter their authentication credentials when they switch from one of your websites to another.
