    Facebook tweaks login for outside sites


    TRYING to become even bigger, and make more money, Facebook will allow users to reveal a little less.

    The social network announced on Wednesday that when its 1.3 billion users log onto other websites or mobile apps through their Facebook identities, they would be able to limit what they revealed to the site or app to just their e-mail addresses and public profile information like name and gender.

    Before, depending on the app or site, the simple act of using the Facebook login exposed much of their Facebook information to the app or site.

    The social network also announced that it was testing a feature to allow people to use their Facebook identities to log onto other sites or apps through a button marked "Log in anonymously".

    Users who chose the button would not be anonymous to Facebook, which would continue to collect information about what apps its users were active on. But no personal information would be revealed to the outside service.

    Both these moves were in response to long-time complaints raised by many users who objected to requests for personal data, and who objected to being asked to log in through Facebook.

    Even Facebook co-founder and chief executive Mark Zuckerberg seemed to share these concerns.

    "I install a lot of apps," Mr Zuckerberg said in an interview at a company conference for application developers on Wednesday in San Francisco.

    "If it looks like it's kind of sketchy, no, I don't want to give it access to my messages and every part of Facebook. I think that's something a lot of people can empathise with, and we just want to give them the tools to help mediate that."

    While the changed rules involving Facebook logins are likely to be popular with Facebook users, app developers would lose access to valuable information about their customers.

    But Facebook is offering them other inducements to work with the social network.

    The company formally announced a new mobile advertisement network that can tap Facebook's knowledge of its users to place targeted ads inside other companies' apps, with Facebook and the app-maker sharing the revenue.

    Facebook has been testing this network on a small scale for several months.

    Google and Twitter offer app developers access to similar ad networks.

    Mr Zuckerberg said Facebook's "Log In anonymously" button would also persuade more people to try new apps.

    "As many as two-thirds of people who download an app don't ever create an account," he said.

    Mr Zuckerberg's long-term goal is to make Facebook a platform on which many other apps run, with Facebook accounts used as a universal identity card to log in everywhere.

    Widespread use of Facebook identities would give the social network valuable data to help sell more ads, its principal source of income; keep users attached to the service; and increase the company's influence in the tech world.

    "The more that people can move through these experiences, the more likely it is that they will want to share content or will want to do something that ends up creating revenue," Mr Zuckerberg said.

    To persuade outside developers to offer Facebook logins on their sites and apps, Facebook had agreed in the past to share information about its users, from birth dates and likes to lists of their friends and even photos.

    That had led to abuses, with games like FarmVille at one point badgering all of a player's friends to sign up to try to increase usage.

    But the policy had also helped Facebook corral about half the market for so-called social logins - although Google is a fast-rising challenger, and LinkedIn and Twitter are popular logins for certain applications.

    The company said that about 10 billion social logins were made last year using Facebook identities.

    Industry analysts said social logins were becoming more popular in part because mobile phone users found it easier to click one button to log in with a social network instead of typing out new account information for every app.

    However, Facebook's user surveys and outside research have found that many consumers were not happy with this system.

    Patrick Salyer, the chief executive of Gigya - which helps about 700 companies manage social logins - said a survey last year by his company had found that nearly half the people it polled had not used social logins.

    "The No. 1 thing that they were afraid of was their data was being sold," he said.

    "Another concern was that their news feed would be spammed without permission or their friends would be spammed without permission."
