Stop stupid devs cow-towing to moronic users incompetence!
The problem is that I've been on websites, forced to sign up, got my password manager to generate a random 20 char password only to be told the password must be 10 chars or less and can only contain alphas and basic ASCII punc marks like underscore and pound!
You know why don't you? People who who do NOT use password managers walk around with one password in their head and the site managers don't need the grief everytime 90% of their user base forget's it's password.
Biting the hand that feeds IT
