Facebook isn’t a company that inspires any level of trust with your data. After it was revealed that Facebook uses ‘shadow contact information’ to allow advertisers to target you with even more invasive ads, and what we’ve already seen with the Cambridge Analytica scandal, it’s probably for the best if you minimise the personal data Facebook has on you. The company first started asking people to store their phone numbers on the service to provide them “better security” via two-factor authentication — essentially a one-time password (OTP) sent to your phone via SMS every time you log in. Recent reports have revealed that it allows advertisers to target you using that phone number too, even though you shared it with the company for security, it has been allowing advertisers to target you via that. Here’s how to remove your phone number from Facebook.
