Introduction
In this lesson, you'll apply your knowledge of arrays and loops to the problem of analyzing password security. It's a great way to practice your skills and to delve into a process you've seen many times online.
Challenge Yourself
Passwords are a fact of life—and, as a user, you should choose yours wisely. But the developers of an app or a service should help their users make good password choices.
Different sites have different rules, but they're all similar in nature—for example, most sites require that passwords have a minimum number of characters.
Get ready to step into the shoes of a developer tasked with protecting the security of user accounts. This kind of coding carries a lot of responsibility. If not done well, a password verification algorithm could allow users to choose insecure passwords, or it could frustrate users with too many rules.
To get started, open Password Security.playground in your course resources and follow the instructions.
Have fun!

How could you encapsulate your password-checking algorithm in a type? Create a PasswordSecurityChecker struct that embodies your rules and can check any password.
