📍 Flask-Based Authentication with Redis

📎 Project Description This project implements an authentication system using Flask and Redis. Additionally, it features WebSocket notifications that inform active users when new accounts are registered.

💻 Development Stack

• Frontend: HTML, CSS
• Backend: Flask
• Database: Redis
• Password encryption: bcrypt
• WebSockets: Flask-SocketIO

📌 Task 1: Static Profile Page

✅ Implemented a static profile page using HTML + CSS.

✅ The page contains a heading, text, and an image.

✅ The design was chosen freely.

✅ The static page is served at the root ('/') and later redirected.

✅ Static resources (CSS, images) are properly served.

✅ Used render_template() for rendering.

✅ / redirects to /login, which further redirects to /profile after authentication.

📌 Task 2: Authentication System with Database

Basic Requirements:

✅ Application listens on localhost:5000.

✅ Login page is rendered at http://localhost:5000/login.

✅ Upon successful authentication, users are redirected to /profile.

✅ /profile is accessible only for authenticated users.

✅ User credentials are stored in Redis.

Advanced Requirements:

✅ Registration feature implemented (/register).

✅ Passwords are hashed using bcrypt.

✅ Logout functionality.

❌ Password change feature is missing.

❌ Profile picture updates are not available (default profile picture is used).

✅ Profile information can be updated.

Challenging Part:

✅ Implemented WebSocket notifications – active users receive messages when a new account is registered.
