Demos

Test password strength using Complexity:
Complexity is an unintelligent test that checks for complexity in a password by looking for a mix of characters, case, symbols, numbers and length. This is useful for encouraging hard to remember complex passwords, but can score easily cracked passwords like `P@s$w0rd` as Strong.

Test password strength using the "zxcvbn" algorithm:
zxcvbn (used by DropBox) is an intelligent algorithm that calculates the guess-ability of a password by comparing it to a large dictionary of common English words as well as looking for recognizable patterns like `P@s$w0rd`. This is a more robust strength checker that allows for user-friendly passwords that are easy to remember but still hard to guess. A Very Strong result represents a password that may take a computer years to centuries to guess.
