⚠️ Common Password Mistakes to Avoid
Even strong-looking passwords can be weak if you:
- ❌ Use personal info like your name, birthdate, or pet’s name
- ❌ Rely on simple patterns like
abc123,password, orqwerty - ❌ Reuse the same password across multiple accounts
- ❌ Use only dictionary words without any symbols or numbers
- ❌ Create short passwords (under 12 characters)
✅ Fix: Always use a random mix of letters, numbers, and special characters — or use a secure password generator to do it for you!
🧠 How Hackers Crack Weak Passwords
Understanding attack methods helps build stronger defenses:
- Brute-force attacks: Try all possible combinations until they succeed
- Dictionary attacks: Use common words or leaked password lists
- Credential stuffing: Reuse leaked credentials across sites
- Phishing: Trick you into revealing passwords via fake pages or emails
