Write your passwords down on paper at night, and indoors. That way enemy satellites won't have the light needed to read your password sheet with high powered lenses. (Unless of course the satellites are imploying infrared night vision technolgy stolen by spies). Then eat this paper, but rip it into little shreds before you do it; if enemy agents catch you eating this paper, a partially chewed piece of paper can be re-assembled after your untimely demise. After you eat your password sheet, drink lots of alcohol (both to cause you to forget sensitive passwords, and to numb the pain from when you sand your fingerprints off). And finally drink a large amount of non-toxic ink. This way if you are indeed caught by agents, the ink will write over your passwrds in your innards and you won't have to worry the Commies hacking your MySpace account post mortem.
