Facebook won't keep your two-factor phone number truly private

The company is under fire for its refusal to allow users to opt out of being found by their phone number when those digits were only supplied for two-factor authentication.

Twitter user Jeremy Burge pointed out, in a thread, that phone numbers could be searched, with "no way to disable" the feature.

He added that, perhaps unsurprisingly, this data is also shared with WhatsApp and Instagram, which means your phone number becomes a unique ID for you.

Facebook told TechCrunch that this is not a new situation, which is true, and we've known that the platform uses phone numbers for ad tracking since last September .

The fact that Facebook accounts are searchable purely with a phone number raises some interesting privacy and security concerns.
