In 2017, Facebook allowed people to use a physical security key to log into Facebook accounts on the desktop for better protection, which helped people keep them safe from malicious attackers.
Facebook now allows people around the world to set up two factors authentication and log in Facebook on iOS and Android mobile devices using a physical security key.
Two-factor authentication is a security feature that helps and protects your account every time you log into your Facebook account from an unknown device by requiring your password and SMS code which is sent to your mobile phone or authentication app.
Physical security keys are very small devices that can easily fit in your keychain. Physical security keys notify each time someone is trying to access your Facebook account from a browser or mobile device, by notifying the owner “we don’t recognize”. In that time Facebook will ask you to confirm it’s you with your key, so the owner can easily recognize someone trying to access information or try to login in, but attackers don’t log in to your Facebook account without a physical security key.
You can easily get a physical security key by purchasing from companies. For example, you can see physical security key examples from Amazon, so you will know how it will look like. It can easily connect via Bluetooth technology or directly connect to your mobile device.
To set up a physical security key on your Facebook account, you need to enroll your physical security key in two-factor authentication within the security and login section of your settings.
