Windows 11 requires a version of TPM 2.0. (although some users have still found a way around this requirement). It is used to generate a cryptographic key that is used to boot your device, so assisting in protecting it from hackers who may attempt to tamper with the sensitive data contained on your computer. While fTPM is incorporated in the firmware of your system, a dTPM, or discrete trusted platform module, is a separate chip installed on your motherboard that performs the same job.
