“More than half of the websites in the study accepted passwords with six characters or less, with 75% failing to require the recommended eight-character minimum. Around 12% of had no length requirements, and 30% did not support spaces or special characters.”
I’ve come across a few sites that require one upper case, one number and one symbol (from a short list). Not at least one of each, no no, precisely one of each. One site even forced the password length to be exact -_-
