There are 2 primary methods to hack passwords: Brute Force and Password Guessing. Of the 2, believe it or not, it is easier to guess someone’s password than to try every combination of letters, numbers and symbols. In a brute force attack, password attempts would progress from: a, b, c; to aa, ab, ac; to aaa, aab, aac; and so on.
The core question is not, “Can my password be hacked?”, but rather “How long would it take?”. That’s where password entropy comes into play for our (the user’s) benefit. Loosely defined, entropy is disorder. Since a brute force attack is a very orderly attack, the more disorder you have in your password = better.
