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.

Mac will ask you to “log in” very early in the boot process to decrypt the disk, I assume it keeps the drive key encrypted with your password somewhere.

That's just not true I have two macs with it enabled on both and it requires a single "normal" password

That's likely because your Macs are using the TPM. Does your Linux machine have a TPM, and are you using it?

I don't think so, they are both intel macs over 10 years old and Macs didn't start adding TPM until 2017. On Mac, when you check the box to encrypt the drive during install you're prompted for an encryption password which you never need to use again unless you remove the drive and put it into another mac (or in my case add a second hard drive and use the original as "extra" storage).

Macs had TPMs before Windows PCs, IIRC.

Yes normal password but it happens super early on mine, and once you log in there is a boot progress bar afterwards. This is an Intel Mac, might be different on apple chips.
