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.

    Correct. The decryption key is stored in the TPM and unsealed when specific criteria match (for example, booted from the correct drive, to the correct kernel file). Figuring out the correct values to tie it to is probably the worst part for a user, if you do it wrong it might just unseal because your EFI firmware binary hasn’t changed, which isn’t all that useful if someone is trying to break in with a live image.
