Two-Factor Authentication in NestJS / MongoDB

Hey there, software enthusiast! If you’re looking to beef up your app’s security, you’re in the right place. Today, I’m excited to walk you through crafting a top-notch two-factor authentication (2FA) system using the awesome combo of NestJS and MongoDB with Mongoose ORM. NestJS is a super cool Node.js framework that makes backend development a breeze, while MongoDB is our go-to for a flexible and scalable NoSQL database. Let’s get started!

NestJS and MongoDB: A Quick Intro

Before we roll up our sleeves, let’s chat a bit about NestJS and MongoDB. NestJS is a modern framework built on Node.js, Express, and TypeScript. It’s like your trustworthy toolkit for building efficient APIs, focusing on modularity and scalability. It’s all about helping you craft server-side applications without sweating the small stuff.

MongoDB, on the other hand, is a beloved NoSQL database known for its flexibility and performance. It stores data in BSON (kind of like JSON), offering nifty querying capabilities. To chat with MongoDB in our NestJS app, we’ll be using Mongoose, an ODM library that makes data handling a piece of cake.

Kickstarting the Project

Alright, let’s get the ball rolling! Ensure you’ve got Node.js and npm (Node Package Manager) on…
