Facebook NFC-Based Password Authentication System | WOW!

0 53

Facebook is world’s largest or biggest social network Site and on 25 Jan 2017, Facebook announced support for security keys, giving users the chance secure their logins with a physical device.

Alongside the standard setup, Facebook also built support for a more experimental NFC login system, the first major deployment of its kind. Security keys work as part of Facebook’s two-factor authentication system, which adds a second layer of defense in case a user’s password is compromised.

Facebook Launches NFC-Based Authentication System to make FB-Secure

The social networking giant currently offers 2FA via a security code for login approvals from a text message (SMS) or by using the Facebook app to generate the code directly on their phone. Now, Facebook has introduced a new security key system that can transmit data via NFC to help log into the social media site through a physical key. This means that NFC-embedded Android devices can now use NFC-capable keys (like Yubico’s) to log into Facebook’s mobile site. The security key system, even though a great step forward, is still in its nascent beginnings.

To make it work, you’ll have to buy a device and carry it with you at all times, usually on a keyring, but the end result is easier and faster than waiting for a code over SMS. A number of services already support security keys under the FIDO specification, including Google, Dropbox, and GitHub.

Facebook Two Way Authentication System

Using security keys for two-factor authentication provides a number of important benefits:

  • Phishing protection: Your login is practically immune to phishing because you don’t have to enter a code yourself and the hardware provides cryptographic proof that it’s in your machine.
  • Interoperable: Security keys that support U2F don’t just work for Facebook accounts. You can use the same key for any supported online account (e.g. Google, Dropbox, GitHub, Salesforce), and those accounts can stay safe because the key doesn’t retain any records of where it is used.
  • Fast login: If you use a security key with your desktop computer, logging in is as simple as a tap on the key after your enter your password.
