JWT (JSON Web Token) Based Authentication

What is JWT authentication service? 

  • Is used to login and logout of the application 
  • Login process 
    • In order to perform login, the client posts user credentials (such as username/password) to the authentication server 
    • If the authentication was successful, JWT token is returned to the client 
    • The client then saves the token in the local storage 
  • After login 
    • Subsequent requests to the resource server sends the token in the “authorization” HTTP request header in order to access secured resource
