TKey
– a new kind
of security
key
The TKey is a small computer in a USB-C device form factor, that can run small applications which are loaded onto it. The purpose of TKey is to be a secure environment for applications that provide a security function. Some examples of such security functions are:
– Time-based one-time password (TOTP)
– Signing oracles
– Secure random numbers
– Encryption
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.

Frequently asked questions
TKey
How do I develop apps for TKey?
All information on developing your own apps for TKey can be found in the Developers Handbook.
How do I adapt TKey to fit my use case?
The way TKey is designed makes it possible for anybody (well, anybody with programming knowledge) to adapt their TKey for their specific use case or own purposes. The way to do that is by developing an own app. From scratch or start with an already existing app and make own adjustments. Read all about developing apps in the Developer Handbook.
What is TKey Unlocked?
TKey Unlocked is a non-programmed TKey.
TKey Unlocked can be used for a customer to program a TKey by themselves and by that have full control of what the TKey contains. This will essentially make such a TKey a user owned USB security key.
Another use case for TKey Unlocked is for developers to experiment with the hardware and/or firmware. The heart of the TKey is a Lattice iCE40UP5K FPGA. TKey Unlocked can be used for experimenting with the FPGA.
All information on how to program TKey Unlocked can be found in the Developers Handbook.
NB 1: A TKey Programmer is needed for programming the TKey Unlocked.
NB 2: App development does not require TKey Unlocked, the TKey is sufficient.
What is TKey Programmer?
TKey Programmer is needed for programming TKey Unlocked.

What is TKey?
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.
