Last week, I tried to register for a service and was really surprised by a password limit of 16 characters. Why on earth yould you impose such strict limits? Never heard of correct horse battery staple?

Ok. Take up to 65,536 bytes of utf8 string. Or better yet. Accept any password length. I mean any. But instead of transmitting it you bcyrpt on their machine and then use the resulting key to hmac sign a recent timestamp that can't be reused.
