I have managed to make it work using the code snippets from the website, but I don't really understand why we need the passport.js as a middleware to do the authentication. JSON Web Token has a broader approval, being mentioned in 29 company stacks & 15 developers stacks compared to Passport, which is listed in 11 company stacks and 11 developer stacks.I am not familiar with user authentication in Node.js, now I am trying to create a website with a login system. Twig World, Redsift, and Para are some of the popular companies that use JSON Web Token, whereas Passport is used by Decision6, University of Europe Laureate Digital, and KOACHR. It seems that Passport with 15.9K GitHub stars and 936 forks on GitHub has more adoption than JSON Web Token with 2.59K GitHub stars and 259 GitHub forks. JSON Web Token and Passport are both open source tools. JSON Web Token and Passport can be primarily classified as 'User Management and Authentication' tools. A comprehensive set of strategies support authentication using a username and password, Facebook, Twitter, and more. Extremely flexible and modular, It can be unobtrusively dropped in to any Express-based web application. It is authentication middleware for Node.js.

This information can be verified and trusted because it is digitally signed Passport: Simple, unobtrusive authentication for Node.js. JSON Web Token is an open standard that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. JSON Web Token: A JSON-based open standard for creating access tokens. JSON Web Token vs Passport: What are the differences?
