Originally, Google offered a 50 bundle with both a USB-A key and a battery powered Bluetooth fob. “In addition to being affordable, we chose Nordic as initial reference hardware because it supports all major transport protocols mentioned by Fido2: NFC, Bluetooth Low Energy, USB, and a dedicated hardware crypto core. The Titan Security Key is a FIDO -compliant security token developed by Google which contains the Titan M cryptoprocessor which is also developed by Google. The USB-C Titan Security Key grew out of Googles earlier Titan key series. Using the code 'B-TITAN35OFF' can take up to 35 off of a purchase of security keys, so you can snag the wireless-equipped key that connects over USB, Bluetooth or NFC for just 3.99 (the price of shipping), instead of 35, or a pair of keys that adds a USB unit, at just under 20 instead of 50 plus shipping. “With this early release of OpenSK, you can make your own developer key by flashing the OpenSK firmware on a Nordic chip dongle,” the company explains in a blog post.


“By opening up OpenSK as a research platform, our hope is that it will be used by researchers, security key manufacturers, and enthusiasts to help develop innovative features and accelerate security key adoption,” says Google. OpenSK is an open-source implementation for security keys written in Rust that supports both Fido U2F and Fido2 standards, and has been developed “to help advance and improve access to Fido authenticator implementations.”

KEY IDEA: Google suggests makers 3D-print a case for their OpenSK hardware security keysĭevelopers and researchers can now make their own Fido-compliant NFC, Bluetooth and USB hardware security keys using new open source software developed by Google.
