Facebook's 29-year-old billionaire creator Mark Zuckerberg speaks on the opening day of the Mobile World Congress in Barcelona, on February 24, 2014
Facebook moved on Wednesday to bolster the trust of its more than one billion users by providing new controls on how much information is shared on the world's leading social network.
In a major shift away from the notion long preached by Facebook co-founder and chief Mark Zuckerberg of having a single known identity online, people will be able to use applications anonymously at Facebook.
The social network also provided a streamlined way for people to control which data applications can access and began letting people rein in what friends can do with shared posts at Facebook.
Mr Zuckerberg announced the changes, along with moves to make Facebook a more stable platform for applications, at the social network's sold-out f8 developers conference.
"By giving people more power and control, they are going to trust all the apps we build and over time use them more," Mr Zuckerberg told an audience of about 1,700 conference attendees.
"That is positive for everyone."
