We appreciate the feedback we've received about these settings and will take it into account.' Today, the 'Who can look me up?' settings control how your phone number or email address can be used to look you up in other ways, such as when someone uploads your contact info to Facebook from their mobile phone.

In April 2018, we removed the ability to enter another person's phone number or email address into the Facebook search bar to help find someone's profile. In a statement sent to CNBC, Facebook said the settings 'are not new and are not specific to two-factor authentication. WhatsApp uses phone numbers as the primary way to set up an account, which could raise privacy concerns for users already surprised by the use of their phone number on Facebook's other platforms. The concern around Facebook's use of phone numbers follows its plans to further integrate its messaging services across Messenger, WhatsApp and Instagram. That means if a user's setting allows 'everyone' to look them up by phone number, even a person without a Facebook account could find their page on the site. While users can hide their phone number from the general public and restrict who can look them up by phone number by switching the setting from 'everyone' to 'friends of friends' or just 'friends,' Facebook does not give the option to get rid of the look-up option entirely.
