Chapter 1: What Are Passwords and Why Do We Use Them?
Big Idea Question:
Why do we need passwords?
Passwords keep our stuff safe by making sure only we can get in!
What is a Password?
A password is a secret word, number, or mix of both that protects important things like your tablet, computer, or even a game account. Think of it like a magic key that only you have. When you type it in, it opens a door just for you. But if someone else doesn’t know the password, they can’t open the door!
Why Do We Need Passwords?
Imagine if anyone could open your backpack and take your favorite book or toy. You wouldn’t like that, right? Passwords stop people from looking at your private things on a computer or device. They help keep your stuff safe and make sure only you can use it.
What Makes a Strong Password?
A strong password is like a superhero shield—it’s hard to guess! Here’s how to make one:
- Use uppercase letters (like A, B, C).
- Use lowercase letters (like a, b, c).
- Add numbers (like 1, 2, 3).
- Use symbols (like !, ?, @).
For example, instead of making your password “cat,” you could make it “C@t123!” That’s much harder to guess!
Connection to Real Life
Think of a password like the lock on your house door. The lock keeps strangers out so that only your family and friends can come inside. Your password works the same way—it protects your computer or device so only you can use it.
How to Keep Your Password Safe
It’s super important to keep your password a secret. Here are some tips:
- Don’t share your password with anyone except a parent or teacher.
- Don’t write your password where someone can see it.
- If you think someone knows your password, tell a grown-up and change it.
Quick Activity
Let’s practice making strong passwords!
- Pick a word, like your favorite animal or a hobby.
- Add a number and a symbol to it.
- Make sure it’s something you’ll remember but hard for others to guess.
For example:
- Word: monkey
- Add a number: monkey12
- Add a symbol: M0nkey12!
Now you’ve created a strong password!
