I've always thought you could predict the characters in a password by looking at the oil/polish on the keycaps.

I always figured this could be an attack someday. But didn't know the tech was cheap enough/sensitive enough yet. I need to start being more paranoid.

Which is why keeping your keyboards wiped down (I use baby wipes) isn't just for compulsives.

It's a hygiene and security best practice.

The oils on my fingers attack the print on my keyboard. After a few years the "home row" is very faded. Fortunately my password is not something I type enough other things that you can figure out passwords out based on this.
