What is a TPM?

A TPM is a small chip on your motherboard, usually separate from the CPU, which works as an authenticator for the computer.

When you turn on your computer, the TPM will generate a unique code (cryptographic key) which will allow the computer to unlock any drive encryption and start up.

If there is a problem with this key, the computer will not boot up.
