About the Password Generator
The Password Generator creates cryptographically random passwords using your browser's built-in secure random number generator (crypto.getRandomValues). Every password generated is unique, unpredictable, and never stored or transmitted.
What Makes a Strong Password
A strong password has three key properties: length, complexity, and uniqueness. Security experts recommend passwords of at least 12 characters that include a mix of uppercase letters, lowercase letters, numbers, and special symbols. Our generator makes it easy to create passwords meeting these criteria.
Password Length Recommendations
- 8 characters: Minimum acceptable length. Can be cracked in hours with modern hardware.
- 12 characters: Good for most accounts. Estimated centuries to brute-force with current technology.
- 16 characters: Recommended for important accounts like email, banking, and cloud services.
- 20+ characters: Excellent for master passwords and high-security applications.
Password Security Best Practices
- Use a unique password for every account
- Never reuse passwords across different services
- Use a password manager to store your passwords securely
- Enable two-factor authentication (2FA) whenever available
- Change passwords immediately if a service reports a data breach
- Avoid dictionary words, personal information, and common patterns
How Passwords Are Cracked
Attackers use several methods: brute-force (trying every combination), dictionary attacks (trying common words and variations), rainbow tables (precomputed hash lookups), and credential stuffing (using leaked passwords from other breaches). Long, random passwords with mixed character types defend against all of these methods.
