Facebook 2FA numbers are also shared with Instagram which prompts you 'is this your phone number?' once you add to FB.

For years Facebook claimed the adding a phone number for 2FA was only for security. Now it can be searched and there's no way to disable that.pic.twitter.com/zpYhuwADMS

The original FB phone number prompt never mentioned "and more". It was shown for MONTHS before a link was added in September 2018 clarifying "actually we'll use this wherever we damn well please"pic.twitter.com/FcOTIZdVf5

Using a phone number to sign up for services has been the single greatest coup for the social media and advertising industries. One unique ID that is used to link your identity across every platform on the internet. That is why every startup wants your phone number.

My personal Instagram account isn't linked to my Facebook. But I am the admin of a page on Facebook which now *requires* 2FA and mobile phone numbers (as of 2018). Here's Instagram ~days~ after giving my phone number to Facebook (for 2FA only)

Every public WiFi network that asks for a phone number to access it? Shared with advertisers. WhatsApp, Facebook, Instagram? Shared. Phone networks themselves: until last month, sharing your exact location by phone number.https://motherboard.vice.com/en_us/article/nepxbz/i-gave-a-bounty-hunter-300-dollars-located-phone-microbilt-zumigo-tmobile …

It's shocking that this one number is used for usernames, authentication (2FA), advertising tracking, geolocation and more. And it's the same piece of info you have to give to a random plumber to come and fix the boiler.

Facebook is now looking to sync all your info between services. Why? Data regulation. Delete a Facebook or WhatsApp account after this integration and they'll keep your data, claiming it's used or needed for Instagram. The trend line couldn't be clearer. https://www.nytimes.com/2019/01/25/technology/facebook-instagram-whatsapp-messenger.html …pic.twitter.com/Q6vibJo3x9

Facebook now defaults phone number search to "everyone". Unless you change this setting, anyone with your phone number can look up and confirm your Facebook profile. Here's where to change it (and no you can't turn it off altogether if using for 2FA) https://www.facebook.com/settings?tab=privacy …pic.twitter.com/PUItHuFZmI

TL;DR: Login-with-Phone-Number is the new Login-with-Facebook. Easy to track, shared between services, it's the key to invisible mesh of your data. Don't do it.

Apple should offer unlimited additional phone numbers that work as inbound SMS lines only. Each time a service requires a phone number, iOS could generate a new number. If Apple is serious about user privacy, this is the next frontier. The current one, really.

When opening Facebook Messenger for the first time, the default action to create a new account is no longer email or username; it’s phone number. The holy grail. The unique ID.pic.twitter.com/f7wPEN9c80

After logging into Messenger, a prompt appears to share contacts. Continuously feeding Facebook info about all your friends, regardless of whether they would grant this level of access.pic.twitter.com/EVJe3LycwS

*Not* giving your phone number to FB is a borderline pointless: they have it anyway. If any of your friends accepts to Messenger or WhatsApp accessing their contacts, Facebook knows your number, no matter what you dopic.twitter.com/0t0omI747I

Getting a few Qs about Facebook saying in 2018 it would disable 'lookup by phone number'. I'm no expert on Facebook privacy settings (is anyone!?) but one thing is clear: either the 2018 statement is misleading or the current settings page is misleading https://newsroom.fb.com/news/2018/04/restricting-data-access/ …pic.twitter.com/ZdZsJKo0Aq

As of March 2019 the settings screen on Facebook reads: Who can look you up using the phone number you provided? This applies to people who can't see your phone number on your profile. (+ the default for me, and many others, was "everyone", despite only providing phone for 2FA)pic.twitter.com/b8BU5TtGP9

"Don't use phone number for 2FA, use an app" 1. Yes, totally 2. App-based 2FA is too difficult for majority of FB users 3. In my particular instance, FB made a phone number (with verification code sent) mandatory, due to being admin of a large page. This won't apply to everyone.

Here’s what appears to be happening. When it comes to personal details like phone #, Facebook distinguishes between the terms “look up” and “search”. Using phone # in *search* was disabled in 2018, but not the ability to “look up” up profile https://edition.cnn.com/2019/03/04/tech/facebook-phone-number-look-up/index.html …pic.twitter.com/2smr11HwSM

Here's what the search/look-up difference appears to mean: What you can’t do now:
enter any phone number to “search” for matching profile/s
What you can still do now: 
Create an address book full of numbers, sync it to Facebook, and “look up” matching profilesDiesen Thread anzeigen -
For anyone who provided a phone number for 2FA (and didn't delve into settings to find that "look up" was enabled for "everyone") that theoretically means a bad actor could dump a phone number list into an address book, sync to FB, and find the real names/pictures of all matches

No matter which prompt appeared on screen, Facebook always considered (and still considers) phone numbers that are added for security to be fair game for other features. Including looking up profiles. You provide your number? We'll use it.pic.twitter.com/op41E4kq8f

"you idiot why would you give FB your phone number" This won't apply to everyone, but in my specific instance, FB *required* it due to being admin of a large page. After continually ignoring it, a final notice informed me the page would be deleted if no phone number was providedpic.twitter.com/ekCAAeT1H2

Here's the end goal IMO. I don't even object to it being a goal. But give users a choice to merge or link accounts, and respect their boundaries when it come to personal data. Not doing that makes it difficult for a rational person to trust that *any* info can be kept private.pic.twitter.com/Tw1oUxRjwE
