Know and understand the differences between strong and weak passwords
4 Networks and the effects of using them
🔒 What is a Password?
A password is like a secret key that unlocks your digital doors. It keeps your accounts safe from unwanted visitors. Think of it as the lock on your bedroom door – the stronger the lock, the safer your room.
🛡️ Strong vs Weak Passwords
Weak Passwords are easy to guess: 123456, password, qwerty. They’re like a door with a single keyhole – anyone can pick it. Strong Passwords combine length, complexity, and unpredictability: G7!pL9z@Q2#. They’re like a door with multiple locks and a keypad – far harder to crack.
💡 How to Build a Strong Password
- Length matters: Aim for at least 12 characters. Longer passwords are harder to guess. Example: 12‑character password = 12! characters.
- Mix it up: Use uppercase, lowercase, numbers, and symbols. Example: A b 1 $
- Avoid common words: Don’t use “password”, “admin”, or personal info like birthdays.
- Use a passphrase: Combine unrelated words with numbers/symbols. Example: Blue Elephant 42 !
- Change regularly: Update your passwords every 6–12 months.
