From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The idea is to use TPM to store the keys - if you boot into a modified OS, TPM won't give you the same key so automatic unlock will fail. And protection against somebody just booting the original system and copying data off it is provided by the system login screen.
Voilà, automatic drive decryption with fingerprint unlock to log into the OS. That's what Windows does anyway.
I see. I don’t know that the usual drive encryption you set up during Linux install works with that, but there are BitLocker-like programs for Linux that might.
I don't suppose you know of a tutorial to get this set up? Google turned up nothing.
Might be pretty complicated. https://www.reddit.com/r/zfs/comments/dimtjv// Your best bet is probably to enable autologin and use the same password for the encryption
Although OPs scenario is if someone steals the tower, in which case it’s not a different TPM. Would only help if the drives were yanked, which honestly I’d probably do rather than try to take the whole tower.
If you boot the computer into the currently installed OS, you will be presented with a login screen and will have to enter the correct password to log in (kernel parameters are part of the checksums, so booting into single-user mode won't help you, that counts as a modified OS). If you boot a different OS, you won't get the key off the TPM.
Yes, but they are asking how to set up FDE in the same way it works on Windows, where automatic unlocking works using TPM. They just don't know the technical details.
