Is there any OS that allows this config?

At least with Linux, if I encrypt my hard drive, I have to enter my encryption password on every login, for some even during boot.

Not sure about Windows. I wpuldn’t be surprised if you can have bitdefender on with auto login.

You can have FDE binded to the TMP and then inside that encrypted volume an encrypted home.

By doing that you only need to input your login password and get better security than the meme setup and other suggestions.

You would need, iirc (I am typing this from memory):

  • A TPM.
  • systemd-cryptenroll
  • Some PAM config for fscrypt or similar.

I know the steps but for NixOS only lmao.
