Turning off authentication

Hi there,

Is there a way to turn off authentication completely on my Mac? I have a 2012 Mac Mini running Catalina and I'm the only person in my household who has access to this computer. I use it for productivity all day long and it's kind of annoying when I have to put my password in for everything I would like to change in settings, be it deleting an app, deleting files from certain folders, changing general settings, etc.

All the topics I found so far was about the 2F authentication and I really need a solution to get rid of passwords completely.

P.S.: I'not afraid of using the Terminal :)

Thanks
