How to Delete JWT Token

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between parties. It is commonly used for authentication and authorization purposes in web applications.

Deleting a JWT token mainly involves removing the token from the client-side. Since JWT tokens are stored on the client side (usually in browser’s local storage or cookies), deleting them is as simple as clearing the associated storage.

Here’s an example of how to delete a JWT token using JavaScript: 

    
      // Clear JWT token from local storage
      localStorage.removeItem('jwt_token');

      // Clear JWT token from cookie
      document.cookie = 'jwt_token=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/;';

In the above example, we use localStorage.removeItem() to remove the JWT token from the browser’s local storage. If the token is stored in a cookie, we need to set the cookie’s expiration date to a past value to invalidate it.

It’s important to note that deleting the JWT token alone does not prevent it from being used again if it has already been compromised. To properly handle token revocation or expiration, server-side checks and mechanisms must be implemented.
