When should I use JWT for authentication?

JWT, or JSON Web Tokens, are useful for stateless authentication in web applications. They allow you to securely transmit information between parties.

What are the benefits of using JWT over traditional session-based authentication?

JWTs are self-contained, meaning they carry all the necessary information, reducing the need for server-side session storage. They also work well in distributed systems.

Are there any downsides to using JWT?

Yes, JWTs can become large if they carry too much data, and if not properly secured, they can be vulnerable to attacks.

In what scenarios would you recommend using JWT?

JWT is ideal for single-page applications, mobile apps, and microservices where stateless authentication is preferred.
