Password Strength Analyzer App

This Password Strength Analyzer is a simple web app to evaluate the strength of a given password based on several criteria. It's important do use a secure password not only for company police but your own personal policy too, so take it seriously. Made good passwords a habit so you can prevent unauthorized access. The more complex the password, the better.

Features

Real-Time Password Evalutation:

Provides instant feedback on password strength, allowing users to make adjustments as they type. Color-coded strength indicator (e.g., Weak, Medium, Strong).

Strength Criteria:

• UPPERCASE LETTERS
• lowercase letters
• Numbers
• Special characters
• Minimum length requirements

Demo

How It Works

Password Input:

The user enters a password in real-time, and the analyzer evaluates the strength based on predefined security criteria.

Strength Assessment:

• The strength of the password is assessed using a combination of factors including:
• Length of the password (minimum 8 characters).
• Presence of both uppercase and lowercase letters.
• Inclusion of numbers and special characters.
• Avoiding common patterns (e.g., "12345" or "password").

Strength Indicator:

The password is assigned a rating (Weak, Medium, or Strong) based on how well it meets the criteria. A color-coded bar gives visual feedback.

Compliant with NIST Standards:

Adheres to modern password guidelines, such as those outlined by NIST SP 800-63B (Digital Identity Guidelines), ensuring that passwords are both secure and user-friendly. This compliance is an impressive aspect for those aiming to work in environments that prioritize security standards.

Installation and Setup

1. Clone the Repository:

git clone https://github.com/your-username/password-strength-analyzer.git

2. Navigate to the Project Directory:

cd password-strength-analyzer

3. Install Dependencies:

npm install

4. Run the Development Server:

npm run dev

Navigate to http://localhost:3000 in your browser to view the app.

Security Features Overview

Entropy Calculation for Password Strength:

Calculates the entropy of the password (unpredictability) and uses this to assign a strength rating. This is more sophisticated than checking for the presence of character types.

Real-Time Suggestions:

Feedback loops guide users towards best practices, helping them create more secure passwords on the fly.

Compliant with Modern Password Policies:

This project demonstrates compliance with guidelines like NIST SP 800-63B.
