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.
Not sure if this works with drive encryption since it comes before the OS, but could this maybe be done with a YubiKey or something like that?
That way, you can plug it in and not worry about typing the password every time, but then it's also secure if someone takes your PC? As long as you remove the key when it's off of course.
Yes, systemd-cryptenroll supports Yubikey as well as generic FIDO2 tokens (and the TPM on most distros).
