Complexify is a jQuery plugin for accurately telling users how secure is their password.
The developer puts the motivation behind this plugin very succinctly:
If your password is 8 characters long and only formed of lower case characters, you need to make it better, perhaps by adding a number or more characters.
If your password is 25 characters long but happens to not contain a number, you shouldn’t be forced by a password security policy to add one, you clearly have a very secure password.
The minimum criteria for a password’s complexity are quite satisfactory: a minimum-security password should take at least 600 years to crack on a commodity machine.
