Just a heads up for anyone using AMD CPUs fTPM, it is completely broken and cannot be used even for "someone stealing your laptop".
A few hours time and a few tools can fully compromise the TPM's secrets. This can be performed by anyone who has a little experience tinkering with electronics, someone who can use a soldering iron for example can almost certainly pull this off.
From my understanding all of the "zen" CPUs are effected except for maybe the very most recent models.
