What are the differences between JWT and cookie authentication?

What are the differences between JWT and cookie authentication?

JWT (JSON Web Tokens) are stateless and can be used across different domains, while cookie authentication is stateful and tied to a specific domain.

Which one is more secure?

Both can be secure if implemented correctly, but JWTs can be vulnerable to token theft if not stored securely. Cookies can be made secure with HttpOnly and Secure flags.

When should I use JWT over cookies?

Use JWT when you need a stateless authentication mechanism, especially for APIs or microservices. Use cookies for traditional web applications.

Can I use both together?

Yes, you can use both. For example, you can store a JWT in a cookie for added security and ease of use.
