Well, since you don't actually enter a password to decrypt a bitlocker device, you can intercept the key data with physical connectors to the TPM
Bitlocker just makes it slightly more tedious to retrieve data. As long as you have all other components intact aswell.
I'm just wondering how many devices still use dedicated TPMs, instead of the ones integrated in the SoC by AMD and Intel. Sniffing a bus inside the SoC must be significantly harder or impossible.
Can I have those please? I think I need it to unlock an old hardrive.
If you uploaded your recovery key to Microsoft, then recovery is probably available in the normal recovery workflow.
Sooo... Is there an alternative to be secure other than switching to another OS? Not that I'm doing anything interesting but I would like to have at least a bit of privacy.
Yeah, just don't enable key upload and this can't happen. Don't link your account either if you want to be more sure.
If your account has already been linked, unlink it and change the bitlocker keys, both regular and recovery. (Easiest way is to entirely decrypt and reencrypt the drive.)
Home edition has this "please sign in to microsoft account to 'finish encryption'" text with a exclamation mark which implies the key is available on the drive unencrypted if you don't sign in, meaning anyone could just access your drive with physical access.
There is no "turning off" the key upload, once you sign in, the upload happens immediately, you can "delete" it later, but like nobody really knows if they ever delete it once they have it.

All the more reason to use Linux. I will be swapping to Cachy or SteamOS Desktop, depending on when and how things play out.
