How Strength is Calculated

Length: Longer passwords = exponentially more combinations
Character diversity: Using uppercase, lowercase, digits, and symbols increases the charset pool
Entropy: Measured in bits — log2(charset^length)
Patterns: Sequential chars, repeated chars, and common words reduce effective strength
