About Password Generator

Password Generator creates strong, random passwords directly in your browser using the Web Crypto API. It ensures your credentials are generated securely without ever leaving your device.

Why secure passwords matter?

Brute Force Attacks

Simple passwords like "password123" can be cracked in milliseconds. A 12-character complex password would take centuries to crack.

Credential Stuffing

Hackers use leaked passwords from one site to unlock accounts on others. Unique passwords for every service prevent this chain reaction.

Best Practices

  • Length is key: Aim for at least 16 characters. Length beats complexity mathematically.
  • Use a Password Manager: Don't try to remember them. Use tools like 1Password or Bitwarden.
  • Enable 2FA: Even the best password can't protect you from phishing or session hijacking.

🔒 Security Note

This tool uses the Web Crypto API (crypto.getRandomValues) which provides high-entropy random numbers suitable for cryptography. Unlike Math.random(), these values are unpredictable and safe for security purposes.
