Standardize JWT for Security (Access) Token
Learn to standardize access control using JWT and how to validate JWT post-authentication.
We'll cover the following
There are two modes we can use while designing an application using REST APIs. These modes are used to pass the information from client to server, and vice versa.
- Stateful mode, so that we can pass some key critical information in our current session.
- Stateless mode, meaning we do not use sessions to store or pass any information between client and server. JSON Web Token (JWT) is a secure way to authenticate users and share the information. Once the authentication occurs via the identity provider, it provides a JWT token, which is valid for a predetermined period and every request post that will pass this token with each request.
JWT does not make everything secure. First, let’s see the structure of JWT, its possible issues, and how we mitigate those issues.
