SMS OTP Sender

This project demonstrates how to send one-time passcodes (OTPs) via SMS using Amazon Simple Notification Service (SNS). It includes a Node.js script that generates a random 6-digit OTP and sends it to a specified phone number.

Prerequisites

Before running the script, ensure you have the following:

• Node.js installed on your machine.
• An AWS account with appropriate permissions to use the Simple Notification Service (SNS).
• AWS credentials (access key and secret key) stored as environment variables or in an AWS configuration file.
• A .env file containing necessary configuration, including phone number and AWS region.

Setup

1. Clone this repository to your local machine:

   git clone https://github.com/adanzweig/nodejs-aws-sns.git
   cd nodejs-aws-sns

2. Install dependencies:

   npm install

3. Create a .env file in the project root and add the following:

   REGION=us-east-1   # Replace with your desired AWS region
   AWS_ACCESS_KEY=your-access-key
   AWS_SECRET_KEY=your-secret-key

Usage

Run the script to send an OTP via SMS:
