What are the differences between JWT and session tokens?

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. Session tokens, on the other hand, are typically stored on the server and are used to identify a user's session.

Which one is more secure?

JWTs can be more secure if implemented correctly, as they can be signed and encrypted. However, session tokens can also be secure if managed properly, as they are stored server-side.

When should I use JWT instead of session tokens?

Use JWT when you need stateless authentication, especially in microservices or when you want to share tokens across different domains. Session tokens are better for traditional web applications where you want to maintain server-side state.

Can I use both in the same application?

Yes, you can use both in the same application. For example, you might use JWT for API authentication and session tokens for web app user sessions.
