How Does JWT Expiration With The Exp Claim Work? Have you ever wondered how web applications manage secure access over time? In this informative video, we'll explain how JSON Web Tokens (JWTs) handle expiration using the exp claim. We'll start by defining what the exp claim is and how it is used to set a time limit for token validity. You'll learn how servers generate tokens with an expiration timestamp in Unix time, acting like a countdown clock that determines when the token becomes invalid. We’ll discuss how setting this expiration helps improve security by limiting the window of opportunity for misuse if a token is stolen.

You'll also discover what happens when a token reaches its expiration date and how servers verify tokens during each request. We’ll cover the process of checking the signature and comparing the current time with the exp claim to decide if a token is still valid. Additionally, we’ll explain the importance of re-authentication and how refresh tokens can help maintain a smooth user experience without frequent logins.

Managing token expiration is a simple yet vital part of backend security. By understanding how to include and validate the exp claim, developers can keep systems protected while providing seamless access for users.
