A username and password is great. To get that you have to fill out a bunch of personal information that most people do not have time for or want to fill out. Soon a person will have 20 email accounts tied to 20 different Facebook, LinkedIn, and Twitter accounts. I guess my goal was to find out how a single piece of information could be used to login to many different sites similar to OpenID or single sign on and be successful. Thank you so much for your comment.
