Node JWT Authentication Tutorial is the topic we will discuss today. The full form of JWT is JSON Web Token. If we want to build a secure web application, then we have to implement Authentication. After that, we need to develop Authorization. There are two types of Authentication you can use in any web application development.
- Session-based Authentication
- Token-based Authentication
JWT-based User Sessions
Let’s start by introducing how JSON Web Tokens can be used to establish a user session: in a nutshell, JWTs are digitally signed JSON payloads, encoded in a URL-friendly string format.
A JWT can contain any payload in general, but the most common use case is to use the payload to define a user session.
The key thing about JWTs is that to confirm if they are valid, we only need to inspect the token itself and validate the signature, without having to contact a separate server for that, or keeping the tokens in memory or the database between requests.
