TKey (USB Security Key)


Short description

The TKey is a small computer in a USB-C form factor that can run small device applications which are loaded onto it. The purpose of TKey is to be a secure environment for applications that provide some kind of security function. Some examples of such security functions are:

  • Time-based one-time password (TOTP) token generators
  • Signing oracles
  • Secure random numbers
  • Encryption
  • 2FA

There is no way of storing a device application (or any other data) on the TKey. A device app has to be loaded onto the TKey every time you plug it in.

Tkey is made by Mullvad

Why I think this tool should be added

Something to keep an eye on. They don’t support U2F/FIDO nor TOTP yet. Applications – Tillitis

TKey is open source hardware and software.

I don’t see a mainstream use for it until FIDO2 is supported, so I don’t think it fits with our audience.

I’ll mark as waiting instead of rejected since I think it is planned Eventually™️ as you said.
