User authentication and authorization are a significant part of any application.

Authentication and Authorization

What is Authentication ?
Authentication is the process or action of proving or showing something to be true, genuine, or valid.
In our case, We want to validate a User to be who they say they are based on what credentials they have provided.

What is Authorization ?
Authorization is the process or action of giving official permission for or approval to (an undertaking).
So this User is who they say they are ? So let’s give them permission to carry out actions on our app based on the scope we have provided.

JWT

What is Jwt ?

JSON Web Token (JWT) is a JSON encoded representation of a claim(s) that can be transferred between two parties. The claim is digitally signed by the issuer of the token, and the party receiving this token can later use this digital signature to prove the ownership on the claim.

JWTs can be broken down into three parts: header, payload, and signature.
