Jake Moore, Cyber Security Specialist at ESET:
“At a time when tighter regulations around data privacy are in the spotlight, allowing anyone to search and connect a phone number to a Facebook account might seem a little out of date. Although two-factor authentication is a necessity for individuals in order to help protect their accounts from being hacked, allowing phone numbers to be searched on one of the world’s largest social databases may not be the best idea.
Rather than using your phone number for two-factor authentication, it is safer to use an authenticator app which doesn’t send the one time code via SMS, so it protects you and your account even further.”
