A type of data portability
technology that enables users of the social networking site
to connect their Facebook account with any partner Web site using a trusted authentication method. Using Facebook Connect, members will be able to use their Facebook identity across the Web, including profile photos, name, friends, groups, events, and more. Facebook Connect also uses what the company calls “dynamic security” which ensures the privacy setting you use will also be used on the third-party Web sites.
