Web Authentication System

Overview

This is a simple web authentication system that allows users to sign up, log in, and log out. The application is built using PHP and MySQL for user registration and login functionality. It utilizes PHP sessions to manage user authentication securely.

Features

Sign Up

Users can create an account by providing a unique username and password. The system checks for existing usernames to avoid duplication. If the provided username is already taken, the user will be prompted to choose another username.

Login

Registered users can log in with their credentials. The system verifies the entered username and password against the database and grants access upon successful login. If the provided credentials are incorrect, the user will be shown an error message.

Logout

Logged-in users can log out from their accounts by clicking on the "Logout" link. The application uses PHP sessions to manage user authentication and logout securely.

Welcome Page

After successful login, users are greeted with a warm welcome message on the "Welcome" page, displaying their username. This personalized welcome message makes users feel acknowledged upon logging in.
