Idea
Password strength scoring tool delivering 99% accuracy and actionable feedback to reduce security risks.
Research Paper
Core Innovation
This paper introduces a hybrid feature engineering approach combining leetspeak-normalized entropy, keyboard pattern detection, and TF-IDF n-grams to capture nuanced password weaknesses missed by traditional metrics. The Random Forest model achieves superior accuracy and interpretability, enabling actionable user feedback beyond standard rule-based meters.
Why It Matters
Traditional password meters often mislead users by missing common weak patterns, increasing vulnerability to breaches. This tool provides highly accurate, interpretable scoring that helps users create stronger passwords, reducing risk and improving cybersecurity hygiene at scale. It transforms password security by combining precision with practical user guidance.

Research Paper Overview
Enhancing Password Security Through a High-Accuracy Scoring Framework Using Random Forests
Summary
This study develops a password strength scoring system using Random Forests and other ML models on 660,000+ real passwords, introducing novel features like leetspeak-normalized entropy and pattern detection. The RF model achieves 99.12% accuracy and offers interpretable feedback to improve user password security effectively.
