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 What matters is randomness and entropy, see https://en.wikipedia.org/wiki/Password_strength#Random_passwords.

Humans can't easily remember or type special characters, they should use a password manager for that or use a random list of words, that is much easier to remember and, with enough words, as strong or stronger than any list with special characters. Only drawback: it is longer.
