You can now lock down your Facebook page using NFC

This week, Facebook announced support for security keys, giving users the chance secure their logins with a physical device.

The social network giant also built support for a more experimental NFC login system, making it the first major deployment of its kind.

Facebook already has Security keys as part of Facebook’s two-factor authentication system, adding a second layer of defense in case a user’s password is compromised.

The security key is a physical device, which is a smart USB drive inserted into the computer whenever you log in.

Currently, availability is only on Android, and users will have to login through the mobile site rather than the app itself. The setup also requires the most recent version of the Google Authenticator app.
