"Your password must be between 8-20 characters and contain an uppercase letter, a lowercase letter, a number, a special character and a haiku about your childhood pet."

The thing that really stumps me is the upper limit (which often is something like 20).

and the blood of a unicorn

@binarybaba I'd hate to write the regex for that.

@Liebe there must be a library...

@Leibi you mean just have a few assertions? Doesn't have to be a big Regex mess

Why don't you just let me choose any fucking pass that I want?

It makes me so angry that I have 5 or 6 patterns of passwords because each site validates them in a different way, and too often I don't remember which I used to create the password for a site.

Cabbage!

8-20
