Okay, so I was wrong about the password thing :-).

Although personally I'll still switch my passwords once a year like I
always have done :-). Old habits die hard.

Though my system is logged like a server should be, even though it's
just a plain and simple desktop on ethernet behind a router & firewall
not moving anywhere.. but I do like to know what my system does. I
probably would detect a break in attempt before they got in :-)
