As a computer hobbyist, I often worry how good my passwords are. I've never seen anything to describe how important it is. This chart and the research is super. My hat off to HIVE!
@PerryM the only thing I do not really like is that this graphic is only going up to 18 characters. I would have preferred if it went up to e.g. 32 chars, at which even numeric passwords would safe against brute-force.
