[kanishgit09]

Expected Features:

1. Detect password strength using basic rules or a library (e.g., zxcvbn or custom logic).

2. Display visual strength indicators (e.g., progress bar or colored line).

3. Show textual feedback such as:

"Weak"

"Moderate"

"Strong"

4. Should update dynamically as the user types.

5. Responsive design compatible with both desktop and mobile layouts.

6. Code must be modular and reusable.

Suggestions for Implementation:
Use a library like zxcvbn for strength evaluation, or implement logic based on:

1. Length

2. Use of uppercase, lowercase, numbers, symbols

3. Common dictionary words

Add a component like a progress bar (div with colored background and width changes).

Color codes:

Red = Weak

Orange = Moderate

Green = Strong

Test Cases:

1. Typing "12345" shows Weak

2. Typing "Pass@123" shows Moderate

3. Typing "V#7uLxY9kP!z" shows Strong

Tech Stack:
Frontend: HTML/CSS + JavaScript or framework (React/Vue/etc.)

Files to Modify / Add:

1. Password input component file (e.g., PasswordInput.jsx, RegisterForm.vue, etc.)

2. CSS/Style file for meter appearance
