Facebook Two-Factor Authentication Has Two-Factored Problem

MOUNTAIN VIEW, Ca. – On Facebook two-factor authentication with phone numbers has a two-factored problem.

First: The phone number you give to Facebook to help keep your account safe from potential hackers isn’t just being used for security. A tweet thread from Jeremy Burge, founder of Emojipedia, on Friday showed that people can find your profile from that same phone number, and you can’t opt out of that setting.

This comes almost a year after Facebook said it stopped allowing people to search for profiles by phone numbers, and about five months after Gizmodo found that the phone number being used for 2FA was also being provided to advertisers for targeted posts.
