# 🔒 Password Strength Checker
A real-time password strength analyzer built with Python and Streamlit. This tool provides instant feedback on password security with advanced pattern detection and animated visual feedback.
## 🌐 Live Demo
[](https://passcheq.streamlit.app/)
## ✨ Features
- **Real-time Strength Analysis**: Instant feedback as you type
- **Advanced Password Checks**:
- Common password detection
- Keyboard pattern recognition
- Repeated character detection
- Sequential pattern detection
- **Visual Feedback**:
- Animated strength indicator
- Dynamic progress bar
- Color-coded feedback
- Detailed security recommendations
## 🎯 Password Criteria
The tool evaluates passwords based on:
- Minimum length (8 characters)
- Presence of uppercase letters
- Presence of lowercase letters
- Numbers
- Special characters
- Additional complexity factors
## 🏆 Scoring System
Passwords are scored on a scale of 0-12 points:
- **Weak** (0-4 points): High risk
- **Moderate** (5-8 points): Basic security
- **Strong** (9-10 points): Good security
- **Very Strong** (11-12 points): Excellent security
## 🚀 Getting Started
### Prerequisites
- Python 3.7+
- Streamlit
### Installation

```bash
git clone https://github.com/clueNA/Password-Strength-Checker
cd password-strength-checker
```
2. Install required packages:
```bash
pip install streamlit
```

4. Follow the recommendations to improve security
## 📊 Security Scoring Details
Points are awarded as follows:
- +2 points: Meeting minimum length
- +2 points: Containing uppercase letters
- +2 points: Containing lowercase letters
- +2 points: Containing numbers
- +2 points: Containing special characters
- +2 points: Extra length bonus
Points are deducted for:
- -3 points: Common password detection
- -2 points: Keyboard patterns
- -2 points: Repeated characters
- -2 points: Sequential characters
## 🛡️ Security Tips
- Use a mix of different character types
- Avoid common words or phrases
- Avoid keyboard patterns (e.g., "qwerty")
- Avoid sequential characters (e.g., "abc123")
- Create unique passwords for each account
- Consider using a password manager
