According to the Microsoft Password checker, “A strong password should appear to be a random string of characters to an attacker. It should be 14 characters or longer, (eight characters or longer at a minimum). It should include a combination of uppercase and lowercase letters, numbers, and symbols.” p00p is Weak, PassamaquoddY is Medium, H0m3rJSimps0n is Strong, and iForg0tmyPa55w0rd is Best. That's the problem with passwords – the longer they are, the more likely you are to forget 'em when you need 'em.
