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.

      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.
