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.

This reply isn't going to be helpful to OP, but thought I might add context for others passing by.

I'm using Arch Linux with LUKS encryption and gdm. As long as my user's password is the same as the LUKS password, I only ever type my password in once.

Just saying that a MacOS-like convenience is definitely possible on Linux.

Fascinating, you don't have automatic login enabled? And I assume this is at the pre-login prompt?

Oof - forgot to mention that I do have autologin configured on gdm 😀

user's password can be totally different from luks password if you're using autologin. You can keep it same but that's totally optional. You can login without entering any password at all if not using luks (or using autodecrypt), you can see that in live isos.
