What is Password Generator?

Password Generator creates strong, secure random passwords using your browser's built-in cryptographic random number generator (crypto.getRandomValues). Your passwords are never sent to any server — they're generated entirely on your device.

How to use

  1. Adjust the length slider (4–128 characters)
  2. Select which character types to include (uppercase, lowercase, numbers, symbols)
  3. Optionally exclude ambiguous characters (0, O, I, l, 1, |) for readability
  4. Click "Generate Password" or the refresh icon for a new password
  5. Click "Copy" to copy to clipboard

Limitations

  • Password length: 4–128 characters
  • Requires JavaScript enabled in browser
  • Uses crypto.getRandomValues — available in all modern browsers
  • Cannot generate passphrases (word-based passwords) — only character-based
  • Strength indicator is a rough estimate, not a guarantee of security

Best practices

  • Use at least 16 characters for important accounts
  • Enable all character types for maximum security
  • Use a different password for every account
  • Store generated passwords in a password manager (e.g., Bitwarden, 1Password)
  • Enable "exclude ambiguous" if you need to read the password aloud or type it manually
