💡 Password Security Tips

🎯

Length Matters

Longer passwords are exponentially harder to crack. Aim for at least 12-16 characters for strong protection.

🔀

Mix It Up

Combine different character types: uppercase, lowercase, numbers, and symbols to increase complexity.

🚫

Avoid Patterns

Don't use predictable patterns like "123456", "qwerty", or sequential characters on the keyboard.

🔐

Use Passphrases

Create memorable passphrases using random words: "correct-horse-battery-staple" is stronger than "P@ssw0rd".
