How It Works

Our password generator uses cryptographically secure random number generation combined with advanced entropy calculations to create truly unpredictable passwords.

🔬 Generation Process

  • • Cryptographically secure random selection
  • • Character pool optimization based on options
  • • Ambiguous character filtering when enabled
  • • Entropy calculation for strength measurement

🎯 Security Features

  • • No server-side password storage
  • • Real-time strength analysis
  • • Configurable character requirements
  • • Professional-grade randomness quality

📊 Password Entropy Explained

Password entropy measures unpredictability using log₂(possible combinations). A 12-character password with mixed case, numbers, and symbols has ~78 bits of entropy, making it computationally infeasible to crack with current technology.

Frequently Asked Questions

How does this password generator ensure security?

Our generator uses JavaScript's cryptographically secure random number generation (crypto.getRandomValues) to ensure true randomness. Passwords are generated entirely in your browser with no server-side storage, and we calculate entropy to measure actual security strength. Each password is unpredictable and suitable for protecting sensitive accounts.

What makes a password strong and secure?

Strong passwords combine length (12+ characters), character diversity (uppercase, lowercase, numbers, symbols), and unpredictability. Our strength analysis measures entropy - a 12-character mixed password has ~78 bits of entropy, making it computationally infeasible to crack. Avoid dictionary words, personal information, and predictable patterns.

Should I exclude ambiguous characters from my passwords?

Yes, especially for passwords you'll type manually. Ambiguous characters like 0/O and l/I can cause login errors when misread. While excluding them slightly reduces entropy, the practical benefits usually outweigh this small security trade-off. For maximum security in automated systems, you can include all characters.

How should I store and manage generated passwords?

Always use a reputable password manager to store generated passwords securely. Never reuse passwords across accounts, write them down in plain text, or store them in browsers without additional security. Enable two-factor authentication where possible, and update passwords immediately if you suspect compromise.
