About Secure Passwords

This generator creates cryptographically secure passwords using the Web Crypto API. All generation happens entirely in your browser - no passwords are ever transmitted or stored on any server.

  • Uses crypto.getRandomValues() for true randomness
  • Entropy calculated based on character set size and length
  • 128+ bits of entropy recommended for high-security applications
  • Longer passwords with diverse character sets are exponentially harder to crack
  • Never reuse passwords across different accounts
