Скачать или смотреть Full Stack Email OTP Authentication System with Nodemailer | MERN Stack Step-by-Step Tutorial

In this tutorial, we will create a full-stack Email OTP Authentication System using the MERN stack (MongoDB, Express, React, Node.js) and Nodemailer to send OTP (One-Time Password) emails. This step-by-step guide is perfect for beginners and intermediate developers who want to understand how to integrate email-based OTP authentication in their MERN stack application.

We'll cover everything from setting up a MongoDB database to building an Express backend with user registration and OTP verification, and finally creating a React frontend for user interaction. We’ll also use Nodemailer for sending OTP emails securely and efficiently.

By the end of this tutorial, you’ll have a fully functional authentication system, with email verification via OTP!
