How Password Strength is Calculated
- Password strength is based on entropy (randomness) and character variety
- Entropy is calculated using: password length × log2(character pool size)
- Character pool includes:
- Lowercase letters (26 characters)
- Uppercase letters (26 characters)
- Numbers (10 characters)
- Special characters (32 characters)
- Time to crack is estimated based on 10 billion guesses per second
- Additional strength factors include password length and character variety
