Updated 2021 MERN stack user authentication tutorial series. In this tutorial series, I'm setting up a project template for working with user authentication in the MERN stack. You will learn to register user accounts to a MongoDB database, log in users on the react frontend and verify logged in users. The authentication is secured by technologies such as JsonWebTokens, Bcrypt and HTTP-only cookies. We'll be using react hooks and the context API to deal with the state management of the user authentication in the frontend.
