How We Measure Strength

Our password strength calculator uses a comprehensive approach that considers:

  • Password length: Longer passwords are exponentially harder to crack
  • Character variety: Using a mix of uppercase, lowercase, numbers and symbols
  • Entropy calculation: A measure of randomness and unpredictability
  • Pattern detection: We check for common patterns that weaken passwords

We also penalize common patterns like sequential characters, common words, and repeated characters.

Why Password Strength Matters

Strong passwords are your first line of defense against unauthorized access. A strong password:

  • Is at least 12 characters long
  • Includes uppercase and lowercase letters
  • Contains numbers and special characters
  • Isn't based on personal information
  • Is unique for each important account

Tips for Better Security

  • Use a password manager to generate and store strong passwords
  • Enable two-factor authentication when available
  • Change passwords regularly, especially for important accounts
  • Don't reuse passwords across different sites
