If you use two-factor authentication to lock down your Facebook account, you can now do it without registering your phone number with the social network, Facebook announced Wednesday, opening its service to third-party tools like Google Authenticator.

Why it matters: "Facebook users are one of the juiciest targets for cyberfraudsters looking to launch mass phishing attacks," according to new data from cybersecurity firm Kaspersky Labs. The more information you put into Facebook, the more incentive you provide for hackers to steal it — so anything Facebook does to streamline securing accounts helps.
