Explanation
A password is like a key to your account. If it is easy to guess, a hacker can open the door. A hacker is a person who breaks into other people’s computers and accounts. A strong password has at least eight characters. It mixes letters, numbers and symbols, and it never includes your name, your birthday or other personal details. Use a different password for each account. If one key opens every door and it is found, all the doors are open. Keep your passwords secret from everyone except a trusted adult. One good idea is to join a few random words and add a number and a symbol. The examples in this book are only for practice, so never use them for a real account.

Worked examples
Pretend password
Characters

7
Camel!7-Moon

Mina counts the characters in the pretend password Camel!7. There are 7. A strong password needs at least eight, so she adds a word and makes Camel!7-Moon, which has 12 characters.
Salma uses the same pretend password for her game and for her school page. A hacker finds it and opens both. One key opened two doors. With two different passwords, only one door would open.
Seif tells his password to his best friend. Later the friend tells someone else. A password is secret. The only person we can share it with is a trusted adult, such as a parent.
Class activity
Treasure box password game. This is practice only, for an imaginary treasure box. Take three cards with random words (for example Moon, Tractor, Sandwich), join them, and add a number and a symbol. Count the characters: are there at least eight? Is there a name or a birthday in it? Show your partner and ask if they could guess it. Then tear up the paper. Never use a practice password for a real account.
