You're here because you want the best security

And we know it

Powerful chip packs a punch. We will use the STMicroelectronics STM32 L4 42KC, which has a ton of goodies: true random number generator for key generation, security isolation for key, onboard crypto, plus two levels of locked flash.

Colorful silicone cases. To protect your security key from physical harm, we researched until we found your favourite colors. Pick any, pick all!

Free updates forever. Any bugs or extensions to our firmware will be available on our website. To update at any time, insert your key and your key will be up-to-date.
