A simple web application built with Flask that evaluates the strength of user passwords and suggests improvements. The application checks various criteria to determine password strength and provides feedback to users.
- Evaluates password strength based on length, character variety (uppercase, lowercase, digits, special characters).
- Provides feedback on whether the password is Weak, Okay, Good, or Strong.
- User-friendly interface for easy interaction.
Python: The programming language used for backend development.
Flask: A lightweight web framework for building web applications.
HTML/CSS: For creating the frontend user interface.
Regular Expressions: For validating password criteria.
-Prerequisites Make sure you have Python installed on your machine. You can download it from python.org.
-Steps to Install
-
Clone the Repository
git clone https://github.com/Joe6001/Password-Strength-Checker-Flask/cd Password_Strength_Checker-Flask -

- Presence of lowercase letters
- Presence of digits
- Presence of special characters
The function returns a score that determines the strength category of the password.
