Vidoop, a company using the OpenID protocol, is out to change the way we “sign on” by eliminating multiple login names and passwords. Vidoop has developed a method by which logging in to any site will require only one username and no password. Its login technology precludes users from having to create new passwords and names through a software-only two factor system.

The system is called Vidoop Secure. It is differentiated by the way it authenticates users; through the use of categorized images. When users sign up for the service they chose a set of secret image categories (dogs, boats, trees etc.) that become their visual password. To sign into a site, users click their image from an ever changing grid of pictures. The result is a secure method of authentication that requires human interaction, yet very little of it.

Vidoop provides web single sign-on using the OpenID protocol, but can also manage your web identities for sites that don’t support single sign-on.
