The way the service will work goes like this: the user’s Facebook profile and log-in information will serve as a web "passport," thus granting the user access to any of the partner websites.

Facebook Connect also gives members the opportunity to broadcast their actions on those sites to their friends on Facebook.

According to an article from The New York Times, during the next few weeks, Facebook Connect will be available on a a number of prominent Web site such as Discovery Channel, The San Francisco Chronicle, the social news site Digg, the genealogy network Geni and the online video hub Hulu.

The idea is similar to that put into practice by Microsoft, when it tried to take its Hotmail service to the next level. However, Microsoft’s password plan came to an abrupt end because of serious user security and privacy issues brough about by third-party sites.

Also, Facebook itself tried something similar with its advertising program Beacon last year in December. The Beacon advertising program stirred a heavy debate over privacy issues after Facebook members were automatically opted-in to the program.

However, Facebook Connect was already tested on some sites such as : CBS, Citysearch, CollegeHumor, Kongregate, Loopt, Plaxo, Radar, Red Bull, Disney-ABC TV, Evite, Flock, Hulu, Seesmic, Six Apart, Socialthing, StumbleUpon, Twitter, Uber, Vimeo and Xobn.
