• Google Friend Connect Help
  Google Friend Connect is a service that helps site owners easily provide social features for their visitors. Users gain the ability to sign in to, make friends on, and interact with your site, making it more social and more dynamic. No programming expertise is required: just paste a snippet of code that we provide onto your site. Learn how to set up your site. As a user visiting friend connected sites, you can become members of sites and interact with other members who share your interests. You can also invite your friends from orkut, Google Talk, and other social networks to join the community. No need to create a new account for the site: simply use your Google, Yahoo!, AOL, or other OpenID account.

And it does this without passing around your password, your email address, or anything you don't want it to. There's no profile exchange component at all: your profiile is your identity URL, but recipients of your identity can then learn more about you from any public, semantically interesting documents linked thereunder (FOAF, RSS, Atom, vCARD, etc.). An OpenID identity is just a URL . You can have multiple identities in the same way you can have multiple URLs. All OpenID does is provide a way to prove that you own a URL (identity) .
