TKey

TKey is a new type of flexible USB security token. TKey is open source hardware and software. Our statement is that all products will be open source, it’s an important part of our core values of being transparent and trustworthy.

Each TKey device contains a Unique Device Secret (UDS), which together with the application measurement, and an optional user-provided seed, is used to derive key material unique to each application. This guarantees that if the integrity of the application loaded onto the device has been tampered with, the correct keys needed for an authentication will not be generated. This allows for open-ended, flexible usage. Given the right application, the TKey can support use cases such as SSH login, Ed25519 signing, Root of Trust, FIDO2, Passkeys, TOTP, and more.
