Improve Your Multifactor Auth With Verify and SIM Swap APIs

This tutorial showcases a security-enhanced system that protects users from SIM Swap attacks by verifying their phone numbers and sending verification codes to prevent unauthorized access to accounts. The application uses the Verify API for authentication and the SIM Swap API to detect recent SIM swaps, which can indicate potential identity theft or takeover risks. The system follows a client-server architecture, with the server-side implementation using Node.js and Express to integrate with Vonage's APIs. The client-side implementation involves HTML, CSS, JavaScript, and forms for user interaction, while the `client.js` file handles form submissions and authentication logic. By implementing this security-enhanced system, users can protect themselves from SIM Swap attacks and ensure secure access to their accounts.
