Trusted Platform Module (TPM) is a chip embedded into a device's motherboard. TPM's provide a way for the device to securely store certain important artifacts like passwords and cryptographic keys.
Trusted Platform Module (TPM, also known as ISO/IEC 11889) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard.
TPM is used for digital rights management (DRM), Windows Defender, Windows Domain logon, protection and enforcement of software licenses, and prevention of cheating in online games.
One of Windows 11's system requirements is TPM 2.0. Microsoft has stated that this is to help increase security against firmware and ransomware attacks.
