  • you immediately tie the permanent accessibility of your local files to you retaining access to a cloud account?

    The Microsoft account holds a backup of the recovery key, which you need to use to restore access in if you do something like significantly change the hardware or move the drive to a different system (which are effectively the same thing).

    You don’t need it for day-to-day use of the system, and you can also just get the recovery key and print it out or write it down somewhere, which is usually how it’s handled on systems that don’t use a Microsoft account.

    Say, Veracrypt is churning away in the background. Why would one leave Bitlocker activated?

    That’s a good point.

    You have different opinions on TPM and the prevalence of evil maids than me, fair

    I work at a big tech company so have to be vigilant even with my personal systems :)

    the premise of the thread

    Some of the things mentioned in the OP don’t actually happen in real life, though. Bitlocker is only automatically activated if you use a Microsoft account to log in, and why wouldn’t you know the account credentials if it’s what you use to log in?

    doesn’t rely on TPM and secureboot silliness

    TPM is optional (but recommended) for Bitlocker. Practically every computer released in the past 10 years has TPM support.

    Secure boot is needed to ensure that the boot is secure and thus it’s okay to load the encryption key. Without it, a rootkit could be injected that steals the encryption key.

    You generally want to use TPM and secure boot on Linux too, not just on Windows. You need secure boot to prevent an “evil maid attack”

    It sounds like you’re complaining about both approaches.

    If Microsoft doesn’t have the key: You can’t recover your files if you lose it.

    If Microsoft does have the key: An attacker could get in and take it (unlikely if you have two factor auth though) and you need to trust Microsoft.

    And Micosoft stores that key in plain text.

    How do you know this, though? It could be encrypted using your account password as a key or seed.
