In the past we’ve warned about the importance of keeping an eye on which Facebook apps have access to your account. In future, that will be all the more important as Facebook has announced that it now lets developers access your phone number and address, if they choose, when you use their apps.
It’s worth noting that Facebook is only making this data available if you specifically approve it – apps you’ve already approved won’t have automatic access to the information. So, next time you install a Facebook app, look out for the “Access my contact information: Current Address and Mobile Phone Number” permission request.
