What is server-side token storage and why is it important?

Server-side token storage refers to the practice of storing authentication tokens on the server rather than on the client side. This is important for enhancing security, as it reduces the risk of token theft through client-side vulnerabilities.

How does it compare to client-side token storage?

Client-side token storage keeps tokens in the user's browser, which can be more vulnerable to attacks like XSS. Server-side storage mitigates these risks by keeping tokens secure on the server.

What are the best practices for implementing server-side token storage?

Best practices include using secure, encrypted connections, implementing token expiration, and regularly rotating tokens to minimize the impact of potential breaches.

Can you give an example of a framework that supports server-side token storage?

Many frameworks support server-side token storage, such as Express.js with middleware for session management, or Django with its built-in session framework.
