About This Password Generator
This generator uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure random number generation. Your passwords are generated entirely in your browser and never transmitted over the network.
Understanding Entropy
- < 40 bits — Weak: crackable in seconds with modern hardware
- 40–59 bits — Moderate: suitable for low-risk accounts
- 60–79 bits — Strong: good for most accounts
- 80+ bits — Very strong: resistant to all practical attacks
Tips for Strong Passwords
- Use at least 16 characters for critical accounts
- Include uppercase, lowercase, numbers, and symbols
- Never reuse passwords across different sites
- Use a password manager to store your passwords securely
- Enable "Exclude ambiguous" if you need to type the password manually
