User Authentication System

The User Authentication System is a secure and reliable mechanism designed to verify user identities and control access to protected resources. It provides a robust solution for authenticating users and ensuring that only authorized individuals can access the system, application, or website.

Features

• User Authentication: Sign up and log in securely to the User Authentication System.
• Token-Based Authentication: Use tokens for authentication and session management.
• User Identification: Register and authenticate users using their email addresses.
• Access Control: Grant authorized access to protected resources based on user authentication.
• Secure Communication: Implement secure communication protocols (e.g., HTTPS) to protect user credentials and sensitive data.
• OAuth2 Integration: Allow users to sign in using their Google accounts via OAuth2 authentication.

Tech Stack

• JavaScript: Programming language used for server-side and client-side development.
• Node.js: JavaScript runtime for server-side application development.
• Express: Web application framework for building robust and scalable apps.
• MongoDB: NoSQL document database for flexible and scalable data storage.
• Mongoose: Object Data Modeling (ODM) library for MongoDB and Node.js.
• EJS: Templating engine for generating dynamic HTML content.
• Bootstrap: A versatile front-end framework for building responsive and sleek web applications.
• Googleapis: Package for integrating with Google services, including OAuth2.

Getting Started

1. Clone the repository:

   git clone https://github.com/Amaan-Uddin/User-Authentication-System.git

2. Install dependencies:

   cd User-Authentication-System

   npm install

3. Set up the MongoDB connection:

   • Ensure you have MongoDB installed and running.
   • Update the MongoDB connection URL in the project's configuration file.

4. Configure JWT tokens:

   • Generate an access token secret and refresh token secret.
   • Update the JWT configuration in the project's configuration file, including the secret keys.

5. Set up OAuth2 with Google:

   • Go to the Google Cloud Console and create a new project.
   • Enable the "Google+ API" and "Gmail API" for your project.
   • Navigate to the "Credentials" section in the Google Cloud Console for your project.
   • Click on "Create Credentials" and select "OAuth client ID."
   • Choose "Web application" as the application type
   • Set the "Authorized redirect URIs" to your callback URL for OAuth2 authentication
   • Click "Create" to generate the OAuth2 client ID and client secret.

6. Configure the OAuth2 client in your project:

   • Create an OAuth2 client with your client ID, client secret, and redirect URI:

     const oauth2Client = new google.auth.OAuth2( 'YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET', 'YOUR_REDIRECT_URI' );

7. Start the server:

   npm start

8. Open your web browser and visit http://localhost:3000 to access the User Authentication System.

Note:

Before running the code on your local machine, set up an .env file with the required configurations:

• DATABASE_URI: The URI or path to your MongoDB database.
• ACCESS_TOKEN_SECRET: The secret key used for generating access tokens.
• REFRESH_TOKEN_SECRET: The secret key used for generating refresh tokens.
• REMEMBER_TOKEN_SECRET: The secret key used for generating remember tokens (i.e. Remember Me Tokens).
• GOOGLE_CLIENT_ID: The client ID obtained from the Google Cloud Console for OAuth2 authentication.
• GOOGLE_CLIENT_SECRET: The client secret obtained from the Google Cloud Console for OAuth2 authentication.
• GOOGLE_REDIRECT_URI: The redirect URI for OAuth2 authentication (e.g., https://developers.google.com/oauthplayground).
