Worst case password

Weak passwords are mostly result of lack of knowledge. Many users have weak password or even worst, easily guessable password.
Users should be persuaded, if needed helped, for usage of strong password. At this age, when electronics are progressing at quantum speed, just use of 6 characters length password and thinking it to be safe, is fools way. Recent study, suggested that in near future, minimum password length should be made 11 characters long. Using 128 bits encryption won’t be enough and service provider should move to 256 bits encryption.
