Facebook Doubles Down on Misusing Your Phone Number

When we publicly demanded that Facebook stop messing with users’ phone numbers last week, we weren’t expecting the social network to double down quite like this: By default, anyone can use the phone number that a user provides for two-factor authentication (2FA) to find that user’s profile. But whether they have to type it into Facebook’s search bar or into their phone contacts, the result is the same: others can use your phone number to find your Facebook profile. (Although Facebook stopped requiring phone numbers for 2FA enrollment last May, phone number-based 2FA can still be the most usable option for many people.)
