+# Multifactor Security Authentication Using Vonage APIs and Firebase Services
+
+## Overview
+
+This project is a web application demonstrating how to strengthen multifactor security authentication using the Vonage SIM Swap API and Verify v2 API, integrated with Firebase Hosting, Functions, and Firestore. The application includes a simple bank dashboard and a login form. If the SIM Swap API detects that a phone number was swapped recently, the verification code will not be sent, and additional security measures will be applied. A verification code will be sent via the Verify v2 API to authenticate the user if no recent swap is detected.
+
+## Features
+
+- A login form to enter and verify a phone number
+- Secure multifactor authentication using Vonage Verify v2
+- SIM Swap detection to prevent compromised logins
+- Simple bank dashboard after successful login
+- Firebase Hosting for serving the application
+- Firebase Functions for server-side logic
+- Firestore for storing user data and verification status
+
+## Prerequisites
+
+- A [Vonage Developer Account](https://developer.vonage.com).
+- A Firebase project set up in the [Firebase Console](https://console.firebase.google.com).
+- Node.js and npm installed.
+
+## Getting Started
+
+1. Clone the repository and change directories
+   ```bash
+   git clone https://github.com/Vonage-Community/demo-sim-swap_verifyv2-javascript-multifactor_authentication-firebase.git
+   cd https://github.com/Vonage-Community/demo-sim-swap_verifyv2-javascript-multifactor_authentication-firebase.git
+   ```
+2. Install the required packages:
+   ```bash
+   npm install
+   ```
+
+3. Move the `.env.example` file to `.env` file in the project root and include the following environment variables:
+   ```bash
+   mv .env.example .env
+   ```
+   ```bash
+    VONAGE_APPLICATION_ID=your_application_id
+    VONAGE_APPLICATION_PRIVATE_KEY_PATH=/path/to/your/private.key
+    JWT=your_jwt_token
+   ```
+
+4. You have the choice to set these variables:
+   ```bash
+    MAX_AGE=your_max_age
+    RECIPIENT_NUMBER=your_recipient_number
+   ```
+
+5. Set up Firebase:
+   - Install Firebase CLI:
+     ```bash
+     npm install -g firebase-tools
+     ```
+   - Log in to Firebase:
+     ```bash
+     firebase login
+     ```
+   - Initialize Firebase in your project:
+     ```bash
+     firebase init
+     ```
+     Select `Hosting`, `Functions`, and `Firestore` when prompted.
+
+6. Deploy Firebase Functions and Hosting:
+   ```bash
+   firebase deploy
+   ```
+
+7. Run the application locally:
+   ```bash
+   firebase emulators:start
+   ```
+
+8. Launch your web browser and enter the URL:
+   ```bash
+   http://localhost:5000/
+   ```
+
+## How It Works
+
+### SIM Swap API
+
+The application uses the Vonage SIM Swap API to check whether a given phone number has been swapped in the last few days. This protects users from attacks that exploit SIM swaps.
+
+### Verify v2 API
+
+The Verify v2 API sends a one-time code to the user's phone number for authentication. This verification code will be sent if the SIM Swap API determines that the number has not been recently swapped.
+
+### Firebase Integration
+
+- **Firebase Hosting:** Serves the web application.
+- **Firebase Functions:** Handles the server-side logic for verifying the SIM swap and sending verification codes.
+- **Firestore:** Stores user data and verification status, ensuring that passwords and other sensitive information are securely managed.
+
+### Application Flow
+
+1. The user enters their phone number on the login page.
+2. The SIM Swap API checks whether the number was swapped recently.
+3. A verification code is sent via the Verify v2 API if no swap is detected.
+4. After successful verification, the user can access the bank dashboard.
+
+This setup provides a robust and scalable architecture, combining Vonage's security APIs with Firebase's comprehensive backend services.
