Instantly measure how secure your password really is. Get a clear strength rating (very weak to very strong), an entropy bits score, and specific tips to make it harder to crack. All analysis happens locally—your password never leaves your device.
No. The entire strength evaluation is performed locally in your browser using JavaScript; ShowPro never sees, stores, or transmits your password.
Entropy bits quantify the randomness (uncertainty) of a password. Higher values mean more possible combinations, making the password exponentially harder to guess.
The score (0–4) is based on a simplified simulation of real‑world cracking patterns (length, character variety, common patterns). While not as precise as the industry‑standard zxcvbn library, it provides a practical assessment.
