APG 2Go generates passwords with two, three, or four random common dictionary words. It displays length and approximate bits of entropy. These types of passwords are among the most difficult to crack during brute-force attacks. Mathematicians have proven that the length of the password is often more important than the complexity. For example, if a person had the password "$3cureP@ssword!" versus a password based on four common yet unrelated dictionary words such as "supermarket-gallery-hang-voyage", the latter would take far longer to crack during a brute-force attack. Additionally, people who are forced to use complex passwords often write them down. However, a password based on four common English words is much easier for someone to remember, and at the same time secure.
