I would be annoyed with a cryptic Audi password. I would prefer 'BatteryHorseStaple' passwords. Anything I can't remember gets written on a post it note and put next to my screen with what it is for. This is my behaviour and the problem with cryptic passwords is that there are others like me, willing to keep a good password secret and not willing to be so secret about a clumsy, easy to crack by machine but impossible to remember password.
