Facebook CEO Mark Zuckerberg announced today that the social media company will amp up its privacy protections — welcome news for users who have come to think of the site as nothing more than personal information mine for advertisers. During a keynote speech at Facebooks F8 Developer Conference, Zuckerberg announced the anonymous login, as a way for users to maintain more control over how much personal information theyd like to share, when they use their Facebook account to log into other apps and websites. Now, instead of just logging into an app through FB, a user can log into an app anonymously. But according to Fast Companys Mark Wilson, Anonymous Login isnt totally anonymous.
