Facebook appears to have U-turned on plans to allow external websites to see users' addresses and mobile phone numbers.
Security experts pointed out that such a system would be ripe for exploitation from rogue app developers.
The feature has been put on "temporary hold", the social networking firm said in its developers blog.
It said it needed to find a more robust way to make sure users know what information they are handing over.
"Over the weekend, we got some useful feedback that we could make people more clearly aware of when they are granting access to this data. We agree, and are making changes to help ensure you only share this information when you intend to do so," the firm said.
The updates would be launched "in the next few weeks", it added and the feature will be suspended in the meanwhile. BBC News
