Titan keys use a choice of USB (you plug them briefly into a USB port), NFC (you wave them near an NFC-enabled device such as a phone) or Bluetooth (same idea as NFC).

This anti-copying feature provides strong protection against attacks such as phishing, where you get tricked into typing in your password on a fake site, and keylogging, where you get infected by malware that monitors your keystrokes and steals your password as you type it in. Simply put, the fact that the key itself not only generates but also securely stores its own cryptographic secrets means that it can’t, in theory at least, be cloned or copied.

The Google Titan device, like similar products from Swedish company Yubico and Chinese company Feitian (which actually makes the hardware used in the Titan), looks like a miniature key fob that contains specialised and supposedly tamper-proof hardware for performing secure cryptographic calculations. Security keys of this sort are often known as FIDO keys after the Fast IDentity Online Alliance, which curates the technical specifications of a range of authentication technologies that “romote the development of, use of, and compliance with standards for authentication and device attestation”.īoldly put, FIDO aims to “help reduce the world’s over-reliance on passwords.”

In July 2018, after many years of using Yubico security key products for two-factor authentication (2FA), Google announced that it was entering the market as a competitor with a product of its own, called Google Titan.
