[KL] Password Tools


This modification mostly follows the principles of Dan Wheelers password strength estimator zxcvbn. It does not weight password strength by their combination of upper/lower letters, special characters and numbers, but on how easy they are to crack in reality.

To increase the safety of your users account, you can force them to use passwords of a minimum length, minimum strength and even force them to exclude certain words from their passwords (like your site name, the topic your site refers to, etc.).

zxcvbn Readme said:
zxcvbn is a password strength estimator inspired by password crackers. Through pattern matching and conservative entropy calculations, it recognizes and weighs 10k common passwords, common names and surnames according to US census data, popular English words, and other common patterns like dates, repeats (aaa), sequences (abcd), keyboard patterns (qwertyuiop), and l33t speak.

Consider using zxcvbn as an algorithmic alternative to password policy — it is more secure, flexible, and usable when sites require a minimal complexity score in place of annoying rules like "passwords must contain three of {lower, upper, numbers, symbols}".

  • Show users how strong their passwords really are when it comes to crack-attempts
  • Deliver instant feedback if password and password-confirm match and/or certain requirements are not met
  • Force users to choose passwords with a minimum strength
  • Force users to choose passwords with a minimum length
  • Force users to chooce a password not containing words from a blacklist you define
  • No cheating: This modification also controls users passwords on server side with Ben Jeavos php-implementation of zxcvbn.

Best addon! This password would be generator or strong a type more than weak type a bit four / five.
Awesome addon, great addition for any forum and it's integrated very seamlessly out of the box. I can't think of any reason not to use this addon :b
Confirmed working on the latest xenforo version 1.5.3! :)

This is pretty much needed for any type of forum.
Great add-on to increase the discipline of password choice. Stable performance and easy to adjust with plenty of style properties out of the box and full customization with CSS.
This is a really nice addon. It works without any problems, is open-source (MIT license) and looks nice.
Great to improve the password strength of the users. Suggestions and improvements are implemented in each update. working perfect in 1.5 Thanks @katsulynx ★★★★★
