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.

Encrypted hard drive asking for password every time (lemy.lol)

I recently switched to Linux (Zorin OS) and I selected "use ZFS and encrypt" during installation. Now before I can log in it asks me "please unlock disk keystore-rpool" and I have to type in the encryption password it before I'm able to get to the login screen.

Is there a way to do this automatically like with Windows or MacOS? Zorin has biometric login which is nice but this defeats the purpose especially because the encryption password is long and tedious to type in.

Also might TPM have anything to do with this?

EDIT: Based on the responses I have to assume some of you guys live in windowless underground bunkers sealed off with concrete because door locks "aren't secure against battering rams". Normal people don't need perfect encryption they just want to add an extra hurdle or two for the crackhead who steals the PC. I assumed Linux had a system similar to what Windows or MacOS has been doing for a decade but I am apparently wrong.

I was kinda annoyed at double password login

Same. Not at all interesting.
Boot up password -> ATA DriveLock password -> LUKS FDE password -> Login password, that's where it's at.

It's just funny situation if you forget the DriveLock master password. Yes, it has 2 passwords. The master password is needed to remove the user password which is used for unlocking. If you forget the master password, you can't ever reset the user password. If you forget both, you upgraded the drive to a paperweight. Additionally, some BIOSes may do hidden key derivation, store the master password in TPM, or do some other crap, so it's generally not recommended unless you actually need it.
This can also be set in hdparm.
Also, I have no idea what way there is for NVME drives, as this uses ATA commands. It's also good to note that some drives use this for hardware-based encryption, and some don't. So it brings varying security.

That's why I have a password manager on my phone.
