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 think this is what I might have to do as I really don't want to go back to Windows. I don't suppose if you know if there is a way to lock the drive upon logging out? Or do I need to do a full shutdown every time.

Move your swap to encrypted part of your drive and suspend to disk. ;)

IIRC and I may be wrong here the drive stays encrypted in sleep. Decryption is done in real time via your CPU. However the encryption key is stored in unencrypted RAM. Which is why the other comment suggests encrypting swap and hibernating, this writes RAM to disk.

I’m not sure LUKs can lock a drive that’s booted already since it’s not a RAM session like a live CD is and relies on the decrypted files to operate. This is why the encryption key is prompted from your boot manager prior to actually getting the system running. That said, I lock my computer all the time and just rely on the normal user password to get back in.
