You can now set up two-factor authentication and log into Facebook on mobile using a security key.
To help you better protect your account, back in 2017, Facebook introduced the ability to set up two-factor authentication and log in using physical security keys. Now, Facebook has brought support for security keys to its mobile apps – iOS and Android – as well.
Typically, logging into your Facebook account from an unknown device on mobile would require you to receive an SMS code, or to use a code generated by the Authenticator app. But malicious hackers have become more effective and sophisticated these days, and the former method has become weaker.
On the other hand, physical security keys are a lot safer, since you’ll need to actually have one on you if you want to confirm a login.
Facebook has supported security keys for the last 3 years but suggests that everyone considers using them to increase security on their accounts. This was previously only possible Facebook on desktop, but now you can use a security key on mobile as well.
Just make sure to choose a security key that supports your device via NFC, Bluetooth, or connector.
In other news, Twitter has started letting you secure your account with multiple 2FA security keys, and even removing other 2FA methods entirely.
