Facebook announced F8 anonymous login facility to use apps.
Facebook News Room Says about:
Today at f8, we announced Anonymous Login, a brand new way to log into apps without sharing any personal information from Facebook, along with a new version of Facebook Login with even better privacy controls.
People tell us they’re sometimes worried about sharing information with apps and want more choice and control over what personal information apps receive. Today’s announcements put power and control squarely in people’s hands:
Anonymous Login: An easy way for people to try an app without sharing any of their personal information from Facebook.
Facebook Login: A new version that gives people the option to pick and choose what information apps get.
A Redesigned App Control Panel: A central place for people to see and manage the apps they use.
Sometimes people want to try out apps, but they’re not ready to share any information about themselves. For this, we’re introducing a way to log in to apps anonymously.
Anonymous Login lets people log in to apps so they don’t have to remember usernames and passwords, but it doesn’t share personal information from Facebook. People can decide later if they want to share any additional information, once they understand more about the app.
We are testing Anonymous Login with a few developers, and we plan to open it up to more developers in the coming months. Read more..
