I’m curious about the possible uses of the hardware Trusted Protection Module for automatic login or transfer encryption. I’m not really looking to solve anything or pry. I’m just curious about the use cases as I’m exploring network attached storage and to a lesser extent self hosting. I see a lot of places where public private keys are generated and wonder why I don’t see people mention generating the public key from TPM where the private key is never accessible at all.
I can’t see that being a reasonable approach for them to take, tbh. One option with TPM is that your system logs in automatically to the desktop, in which case they can just turn it on and use it normally. The other is that it requires a password at some point during startup, to which they could just use a (hardware) keylogger.
It only at most auto logs you into the display manager or more generally into login. Then you still need to get root access to modify anything from there. Login would still be based on user password/key/whatever.
