Without going into terribly geeky depth, the kind of things the TPM is used for include: The TPM can be used for a myriad of security-related functions.
The overarching goal of a TPM is to enable greater security for the computer, as well as for any security-related applications that choose to use TPM. The key words in that description are secure and cryptographic. Per Wikipedia, it’s “a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.” TPM: Trusted Platform ModuleĪ TPM is a hardware component of your computer. Running “tpm.msc” is a quick way to determine the status of your machine’s support for TPM. Most computers manufactured in the last five or so years will have support for TPM 2.0, though it may need to be enabled in the UEFI/BIOS. The Trusted Platform Module is a hardware device that implements several security and cryptographic functions in ways that are more secure and resilient than performing those functions on the PC itself.
