For two years, Facebook has allowed users to implement a more secure connection to the site. But it hasn't been the default for all users until today, when Facebook announced that it would move all of its 1 billion-plus users to Web browsing using HTTP Secure, or HTTPS. HTTPS is a more secure connection between browsers and the Web servers companies like Facebook run.
In a statement made today on its website, Facebook reported that all traffic to www.facebook.com, the version of its site used by most desktop PCs, and 80% of traffic going to m.facebook.com, its mobile website, will be secure. The social media giant says that it's not as simple as adding an "s" to the end of "http," in its Web address. It outlined in-depth steps it had to undertake for the migration, and planned improvements for the fall.
