Why use a password generator?

Human-chosen passwords are predictable. A password generator creates truly random combinations that are statistically resistant to brute-force and dictionary attacks.

Password strength guide

  • 12+ characters — minimum for important accounts
  • Mixed case + numbers + symbols — maximum entropy
  • Unique per site — never reuse passwords
