Password security
If nothing else, it's a good way to indicate how adding variety and especially length to a password can make it very difficult to break.

Neat. And interesting. My 'standard' password has 4 numbers, 4 letters and a punctuation mark (not in that order) and the site said it would take about 2 days to crack it. I then tried a simple 5-letter word with four digits after it, and the site said it would take about 4 days to crack that. I would have thought a dictionary word with 4 digits behind it would be much easier to crack than my gibberish one with punctuation.
That is very interesting. Your observation piqued my interest, so I tried a random 9 character number-letter-symbol password and got a 108 day crack count. Maybe part of the combination of numbers, letters and symbols in your password is a known 'substitute' code for a dictionary word. For example, 3n1gm4 is barely more secure than enigma. I don't know. Most 9 digit combinations I tried that included at least one symbol had a crack count of 108.
Not sure why I came up as 'unknown' previously.
So...something like this 39duwq!50 has 108 day estimate, but 31ujet!6 has a 2 day estimate. Experimentation shows that it is the one extra digit that does it. If I change 31ujet!60 to 31ujet!62, it goes back to 108 days.
I'm not sure why or how that estimate is arrived at...
Must be the 'new math'....
