Security Analysis

Password Strength Checker

Analyse passwords using entropy scoring, breach intelligence, pattern detection, and real-world attack modelling to identify weak or compromised credentials.

Passwords remain one of the most common attack vectors in modern systems, with weak, reused, or breached credentials responsible for a significant proportion of account compromises. Simply meeting minimum length requirements is no longer sufficient to protect users or infrastructure.

This Password Strength Checker evaluates passwords using entropy calculations, known breach data, pattern analysis, and realistic attack models. It helps determine whether a password is weak, predictable, previously compromised, or vulnerable to brute-force and dictionary attacks.
