Password Strength Estimator – Crack Time & Entropy Tool

πŸ” Password Strength Estimator

Strong passwords are the foundation of digital security. Weak, reused, or guessable passwords account for a significant portion of breaches worldwide. This tool offers a quick, interactive way for users to evaluate how strong their chosen password is. Whether you’re creating a new login or auditing existing credentials, knowing the character variety and resistance to brute-force attacks is essential for personal and enterprise safety.

Our estimator uses length, uppercase/lowercase balance, digits, and symbols to calculate entropy. Then, based on that entropy, it estimates how long it would take for a brute-force attack to crack the password. Everything runs client-side, so no sensitive data is ever transmitted. Ideal for security courses, signup forms, UX enhancements, or general user education.
