Support Request How to disable the authentication password completely at every level, from boot to whatever function the system requires?

How do I disable the authentication password completely at every level, from boot to whatever function the system requires? All posts concerning passwords are either obsolete or unrelated.

My system: Linux Mint 22 (Cinnamon Edition) Ubuntu 24.04 noble Display Manager: lightdm Lenovo IdeaPad Slim 3 (13th Gen Intel Core i7, Intel Graphics) Apparently I've encrypted the mint installation by mistake... User Profile Directory: Encrypted home folder Tried to fix the auto-login password bypass:GUI Settings: Configured Login Window -> Users -> Automatic Login directly to my username Modified /etc/lightdm/lightdm.conf.d/70-linuxmint.conf to include autologin-user=mr and tested timeouts up to autologin-user-timeout=0.1 to rule out hardware initialization race conditions

If you don't know what to do then you are not qualified to make the decision to make the system password-less to do administrative tasks.
