Are you a developer who just learned how to build a basic web application using Node.js and Express? Great! However, most apps don’t operate in a vacuum. Apps need to allow users to log in, enable different access for users based on permissions, and make secure requests to other apps. If you want to make your application production-ready, implementing authentication and authorization is absolutely necessary.This course will teach you how to leverage npm libraries to implement authentication and authorization into your app. You will learn how to securely encrypt and store passwords, implement web sessions, and authenticate with social media accounts like LinkedIn and Twitter. You will become familiar with new and sometimes intimidating terms such as OAuth, JWT, and CSRF.This course is taught by a Node.js expert who has built secure, production-level apps that have served over 50 million users worldwide. If you have taken Introduction to Node.js on edX then this course will be a great follow up to advance your knowledge as a Node.js engineer.
