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.

OP, just change your encryption key to whatever you have your password as and set your login to auto login. This will give you the experience you desire as it'll decrypt the disk with your password and log you in automatically once it's decrypted, but if you lock the system (close the lid. Screen lock. Etc) you'll still get a login screen as normal. (Just keep in mind they're technically two separate passwords and will unfortunately need to be changed separately if you do change your password).

    What I do for a little extra security is that my encryption password is just a longer variation of my normal password. So of I have an encrypted password sentence like "correct battery staple horse" my login password would just be "correct battery". It's a simple way to add a little extra and a good reminder everytime I turn on my computer that they are in fact two different passwords and protect me differently.
