Strong Password

A strong password is one that is designed to be hard for a person or program to discover. Because the purpose of a password is to ensure that only authorized users can access resources, a password that is easy to guess is a security risk. Essential components of a strong password include sufficient length and a mix of character types. When people create passwords, they often defeat the purpose by choosing parts of their names, the names of their pets, or even the word "password."
