There is a great deal of misunderstanding, and some misinformation, about the Trusted Platform Module (TPM); to combat this, Debian developer Jonathan McDowell would like to clear the air and help users understand what it is good for, as well as what it's not. At DebConf25 in Brest, France, he delivered a talk about TPMs that explained what they are, why people might be interested in using them, and how users might do so on a Debian system.
