How JWT is used in API security?

In a nutshell, JWT works like this:

  1. The user/client app sends a sign-in request.
  2. Once verified, the API will create a JSON Web Token (more on this in a bit) and sign it using a secret key.
  3. Then the API will return that token back to the client application.
