The Password Generator is a free, easy-to-use tool that helps you create strong, secure passwords based on your preferences. It lets you control the length, quantity, and types of characters used. This ensures that each password is unique and harder to guess or crack, providing stronger protection for your online accounts.

Password Strength Formula

Password Strength Score = Length Score + Character Variety + Uniqueness Bonus + Entropy Estimate
