Even for those aware of the ability to look up Facebook users by searching a phone number, it's come as a shock to find out this also includes the phone numbers in some cases given only for account security. A Facebook spokesperson told TechCrunch that the settings are "not new" and went on adding that, "the setting applies to any phone numbers you added to your profile and isn't specific to any feature". "We appreciate the feedback we've received about these settings and will take it into account".
It is worth noting that Facebook set the "look up" settings to Everyone by default. First and foremost, there's a good reason to suspect the social networking service's two-factor authentication feature is about further weakening user privacy much more than it is about strengthening security.
Facebook gives you the option to limit how people can search for your profile using your personal information.
Facebook had partly disabled such phone-number searches in the past, preventing people from finding someone's profile directly from their number: in April 2018, the ad biz said it had switched off phone number search following the Cambridge Analytica scandal, citing abuse.
He also revealed that the company shares 2FA phone numbers with its other platforms, like WhatsApp and Instagram.

Honsal said the mother was taking care of household tasks when at around 3 p.m. she realized that her daughters were missing. The searchers included National Guard members from Fresno and the U.S.
To be fair to Facebook, you don't need to offer up a phone number to engage two-factor authentication.
'Now it can be searched and there's no way to disable that'.
Users have taken to Twitter to complain that this means Facebook has been using people's phone numbers to help them find each other when uploading their contacts - and there is no way to opt out.
Facebook has been encouraging users to enable two-factor authentication to boost the security of their accounts, but it turns out that there's a slightly sinister side to this feature.
Sadly, the same can't be said about Facebook.
Burge, who is the moderator of Emojipedia's Facebook page, was required to enter his phone number because of the number of followers that page has, and rapidly became frustrated with the lack of privacy he was afforded as a result. FB can't credibly require 2FA for high-risk accounts without segmenting that from search & ads.
