Encrypted hard drive asking for password every time
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'm also a linux noob, but I thought having to unlock the encryption before getting to the actual account was part of the point. If the encryption is always already unlocked it's easier to break in.
Then how come Windows and MacOS don't require two different PWs?
They give up some security by gaining convenience and slightly better UX.
I can't vet Apple's security, but TPM isn't a silver bullet either.

Yeah I don't need a silver bullet I'm not storing highly sensitive data, I just mistakenly assumed this would be easier.
Great to hear. TPM is totally usable if your threat model can tolerate the risk. Sadly Linux is a bit lacking support for TPM in FDE. You can try the Nitrokey with GPG method without pin I wrote in the other thread if you hit the wall. Good luck!
Here's a guide if you want FDE with TPM: https://blastrock.github.io/fde-tpm-sb.html
You keep bringing that up. Those are different systems with different approaches to security. You can compare them to death and back and it won't bring your system to where you want it.
People have come to you with suggestions to achieve what you want and explained the consequences. Try that instead.
