**Phone Number Authentication using Node.js, Flutter, and Vonage SMS Gateway Service API**
[](LICENSE)
## Overview
This project demonstrates how to implement phone number authentication using Node.js, Flutter, and the Vonage SMS Gateway Service API. Phone number authentication provides a secure and convenient way for users to verify their identity during the login process.
## Features
- Generate and send OTP via SMS to users for phone number verification.
- Validate the OTP entered by the user to authenticate their identity.
- Integration with the Vonage SMS Gateway Service API to send and receive SMS messages.
## Technologies Used
- Node.js
- Flutter
- Vonage SMS Gateway Service API
## Setup Instructions
### Prerequisites
- Node.js should be installed on your machine.
- Flutter SDK should be installed.
- Sign up for a Vonage account and obtain the API key, API secret, and virtual phone number.
### Backend (Node.js)
1. Clone the repository: `git clone https://github.com/Danitilahun/flutter-node-otp-phone-number-verification.git`
2. Navigate to the `backend` directory: `cd API`
3. Install dependencies: `npm install`
4. Configure the Vonage API credentials in the `.env` file.
5. Start the Node.js server: `npm start`
### Frontend (Flutter)
1. Open the `otp_verification` directory in your preferred code editor.
2. Configure the backend server URL in the Flutter code.
3. Run the Flutter application on a connected device or emulator: `flutter run`
## API Endpoints
- `POST /auth/send-otp`: Sends an OTP via SMS to the user's phone number.
- `POST /auth/verify-otp`: Verifies the OTP entered by the user.
## Usage
1. Launch the Flutter application on your device/emulator.
2. Enter your phone number and click on the "Send OTP" button.
3. Receive the OTP on your phone.
4. Enter the OTP in the application and click on the "Verify" button.
5. If the OTP is valid, the user is successfully authenticated.
