Facebook Uses Your 2FA Mobile Numbers For Ad Targeting, Not Security

It'southward been a terrible year for Facebook's reputation, having been dented by allegations of election manipulation in 2017. While the Cambridge Analytica revelations before this year, which supported those allegations, shook the world and the company, it'southward been a abiding stream of controversies surrounding the company's many privacy missteps.

The latest one, believe information technology or not, is so bad, that information technology'south used largely by admittedly scummy  companies and apps merely looking to harvest daya. Facebook has been using its vast pool of mobile numbers submitted past users for two-factor authentication and allowing advertisers to target these numbers by adding them to their Facebook audience database.

And so now not only does Facebook know what you like, whom you interact with, the brands yous love and the ones you hate, your political affiliations, your location and photos for facial recognition, but also has the telephone number to deliver all those targeted ads straight to your telephone through diverse apps that may also have access to your number.

Gizmodo reported that Facebook has been using the 2fa mobile numbers for ad targeting. The publication worked with researchers in US universities who were studying how Facebook creates shadow accounts. The author wrote, "I was helping him (Mislove) test the theory by targeting him in a way Facebook had previously told me wouldn't work. I directed the ad to display to a Facebook account connected to the landline number for Alan Mislove's function, a number Mislove has never provided to Facebook. He saw the ad within hours." Mislove is one of the researchers studying Facebook's data drove practices.

Only getting a landline number tin be cumbersome if you lot are talking about billions of users. What ameliorate style to become mobile numbers than request users to manus you their mobile number under the guise of improved security. As the investigative story says once Facebook gets your mobile number, your number becomes targetable past advertisers within a few weeks.

Facebook pretty much confirmed Gizmodo's story today. A Facebook spokesperson told Techcrunch, "Nosotros use the information people provide to offering a better, more personalized experience on Facebook, including ads. We are clear about how we utilize the information nosotros collect, including the contact information that people upload or add to their own accounts. You can manage and delete the contact data y'all've uploaded at any time."

If that token stock response is not indication enough that it's time to go rid of Facebook forever, I don't know what else it might take. Of course, one can debate that Facebook has plugged the hole at present and that you can sign up for 2-factor hallmark fifty-fifty without a mobile number, thanks to authenticator apps – here's how you can do that.

In fact Facebook admitted that it had a 2FA related problems which spammed users with SMSes, which could be related to this very aforementioned method that Gizmodo reported on.

Facebook is caught lying fourth dimension and again, but everytime it gets abroad with its hands in the proverbial cookie jar, information technology boldly raids some other i, and so the cycle continues. At this signal, I am not even sure there's anything good near Facebook, just #DeleteFacebook volition fall on deaf ears, and people will go along to trust the company run past a CEO who once chosen those very users "dumb fucks".
