about Google Titan USB Security

Google introduced the Titan Security Keys at the  Cloud Next ’18 convention in San Francisco.

The Titan Security Key is a tiny USB device that offers hardware-based two-factor authentication for online account sign-ins with the highest level of protection against phishing attacks.

The security keys were earlier tested with and by Google’s employees internally for a couple of months and they discovered that none of them fell victim to phishing attacks.

The Titan USB security key prevents phishing attacks, man-in-the-middle attacks and several other account takeover attacks.

With this, when someone steals your password and attempts to sign in without the physical Titan USB security key, it won’t work.

The USB security key is physical and enables authentication into accounts in addition to the provision of a password.

You have to carry it with you and in case you want to access your email via any PC, you simply log into your account and then, Google or Gmail will prompt you to fix the Titan security key in any USB port.

You will then be prompted to press a button or tap on it once activated.

These security keys may also be used with several online platforms like Google, Facebook, Firefox, and Chrome among others, and they may be acquired at a price of about $30-$40.

How it works

FIDO Security Key

The HyperFido U2F Security key enables seamless authentication to websites and browser-based applications such as Gmail.

You can use your FIDO U2F device across all online services that support the protocol by leveraging built–in support in web browsers.

The FIDO protocols use standard public key cryptography techniques to provide stronger authentication.

During registration with an online service, your device creates a new key pair which retains the private key and registers the public key with the online service.

Authentication is done by the device proving possession of the private key to the service by completing a challenge.

The private key can only be used after locally unlocking the device; which is accomplished by pressing the button on the HyperFido.

The FIDO Alliance includes leading global organizations such as Alibaba, ARM, Bank of America, Discover, Google, Lenovo, MasterCard Microsoft, PayPal and Visa Inc.
