Bitlocker, Yubikey and TPM?
Hi,
I want to protect the data stored on the hard disk drives of my PC.
The purpose is:
* to prevent someone physically accessing my PC and pluging a bootable USB stick from reading/modifying the content of my HDDs
* to prevent someone from reading/modifying the content of my HDDs if they physically pull my HDDs out of my PC and put them in another PC
1/ I think Bitlocker is the way to go: it's free and already built-in Windows.
I already gave Bitlocker a try on another older PC and I like it but in order to guarantee a strong level of security, Bitlocker must use a strong password, which is a pain to remember and a pain to type each time the PC boots. Not to mention I will have to type this PW every time I want to open a bitlocked partition (all partitions will be bitlocked).
2/ This is why I plan to buy a Yubikey, but I'm not sure I can have it working the way I want.
What I want is: everytime I boot the PC I have to plug the Yubikey in a USB port of my PC so that Bitlocker is automatically unlocked without the hassle of typing a Password. And when I open File Explorer, I can open every bitlocked partitions just like if they were not encrypted with Bitlocker as long as my Yubikey is still plugged in.
Can you tell me if it's doable? I find most of Yubikey tutorials being hard to understand and before I choose to buy a pair of these, I want to make sure it will work as expected.
3/ I also have concerns about TPM. This subject is a bit unclear to me as well. I read this thread, but still didn't manage to perfectly understand it: Verify Trusted Platform Module (TPM) Chip on Windows PC
I have an Asus Prime TRX40-Pro S mobo, with a AMD Threadripper 3990X cpu. Here is what the Powershell get-tpm command says:
My question is: say in the future I replace my motherboard, or I replace my cpu. Will I still be able to read the content of my Bitlocked HDDs? (as I guess by replacing these hardware components, the TPM keys will change as well)
Or, which is a bit the same, if I pull out the HDDs of my PC and I plug them into another PC, will I be able to read them?
Given I have the Yubikey of course.
It's an interesting but hard topic to me so I hope all of this makes sense
Thank you in advance for your answers,
Windows 10 Pro version 21H1 (OS Build 19043.928). I am currently installing Windows and the PC is not connected to internet yet, this is why Windows is not up to date yet.
