Ask HN: What font do you use to print sensitive passwords?
From time to time I have to assign complex passwords and give hard copies to users. Notepad font routinely confuses them. They mistake a lowercase l for a 1, etc. Which font is clearest? Look into fonts optimized for source code, like https://www.google.com/fonts/specimen/Source+Code+Pro If you have control over how the passwords look, you maybe also could adjust their generation to avoid hard-to-distinguish sequences. alternative: make your password-generation algorithm avoid letters and numbers that are easily confused.
