Facebook Extends Security Key Support on Mobile Devices

Facebook has revealed that it is introducing hardware security keys support to iOS and Android mobile devices around the world, enabling users to set up two-factor authentication. Since 2017, Facebook users have been able to log into their accounts on desktop using physical security keys to help secure their details from malicious hackers.

Two-factor authentication is a security feature

Two-factor authentication is a security feature that helps secure users' accounts when they log into Facebook from an unfamiliar computer by needing something only they know (their password) and something they have (their phone) (typically, an SMS code sent to their mobile phone or Authenticator app). It's much more difficult for a bad actor to obtain both factors, so their password isn't their last line of defence against phishing or other malicious attempts to steal their data.

Physical security keys

Physical security keys, which are small enough to fit on a keychain, warn users when someone attempts to access their Facebook account using a browser or mobile device that Facebook does not know.

“Since 2017, we've encouraged politicians, public figures, journalists, and human rights defenders who are at high risk of being targeted by malicious hackers. We strongly encourage all, regardless of the computer they use, to consider using physical security keys to improve the security of their accounts.” Facebook reported in a newsroom update.

Security keys can be bought directly from manufacturers (Facebook does not produce hardware keys). The keys can be used with Bluetooth technology or by plugging them into your phone directly. Within the Protection and Login section of their Settings, users can enrol their security key in two-factor authentication.
