i don't get how certain websites have limits on password length or restrictions on which characters you can use. let me use my 20+ character jumbled nonsense from lastpass, damnit!
Rules on what you can use in passwords are a constant source of annoyance. Most of all when they don't tell you them in advance, requiring you to discover them through trial-and-error attempts at creating passwords. And when they impose a length restriction yet allow you to enter more characters than that length, only to _then_ tell you it's too long.
I can't remember which site it was, but I once had a site change their rules on allowable login names, thus invalidating my existing one (on the grounds under their new rules it was now too short) - but not allowing me to change it. Nor could I create a new account because it told me there was already an account with that email address - the one I could no longer use.
