Cyber security experts often talk about how a strong password must be at least $7$ characters long to be considered a strong password and prevent hackers from cracking it$.$

Suppose you are overseeing the implementation of a new password policy at your company for company accounts. Management wants the minimum password length requirement to be $6$ characters, so they are easier to remember, but you are advocating for a minimum character length of $7.$

In $4-5$ sentences, calculate and describe why increasing the password minimum from $6$ to $7$ characters will improve company account security. Assume that any of the following characters can be used to create passwords and that characters may be used more than once:

$$ Lower case letters

$$ Upper case letters

$$ The numbers $0-9$

$8$ different special characters
