If you are trying to take online security seriously today, there is no better way to keep your accounts secure than using physical security keys. A few months ago, Twitter stepped up and added support for two-factor authentication keys on mobile devices, and now it’s Facebook’s turn to do the same. As of today, the company now allows users to register and use hardware security keys on Android and iOS.
This is a feature that Facebook has supported on desktops since 2017, so expansion to phones is long overdue. To enroll your key in the application, go to the Security and Login section in the settings and select Security key under Two-factor authentication. The keys can unlock your account wirelessly via Bluetooth or by physically connecting to the phone for a wired connection (connection using NFC is not currently supported).
It seems that the feature’s launch is still in progress, considering that I was unable to start registering a security key in the Facebook Android application without an error appearing on the screen.
In the ad, Facebook recommends that all users switch to physical keys for two-factor authentication on their accounts, regardless of the device you’re using and whether or not your account is at high risk of being hacked. If you do not have a hardware key, the application will continue to support other 2FA methods, such as authentication applications, text message verification and recovery codes, although none of them are as secure as a real key.
