Lesson 3: Passwords & Accounts
A password is like the key to your house — you wouldn't give it to a stranger! Learning to create strong passwords and keep them safe is one of the most important computer skills.
Key Concepts
What Makes a Strong Password?
A strong password is LONG (at least 8 characters), uses a MIX of letters, numbers, and symbols, and doesn't use your name or birthday. Bad: 'password123'. Better: 'BlueDog$47!'
Keep It Secret!
Never share your password — not even with friends. A good rule: only you and a parent should know your password. If someone asks for your password online, that's a red flag!
Usernames vs. Real Names
Pick a username (screen name) that doesn't include your real name or age. 'CoolRocket42' is safer than 'AlexSmith2016'. Your username is what other people see online.
