Is JWT more secure than sessions?

JWT is secure, but it is at the same time less secure than session based authentication. For example, the JWT is more vulnerable to hijacking and has to be designed to prevent hijacking. An unexpiring JWT can become a security risk. You are also trusting the token signature cannot be compromised.

Which is better JWT or sessions?

In modern web applications, JWTs are widely used as it scales better than that of a session-cookie based because tokens are stored on the client-side while the session uses the server memory to store user data, and this might be an issue when a large number of users are accessing the application at once.

Is JWT good for sessions?

Although JWT does eliminate the database lookup, it introduces security issues and other complexities while doing so. Security is binary—either it’s secure or it’s not. Thus making it dangerous to use JWT for user sessions.

Is JWT less secure?

Local storage is not as secure as using cookies (reference) but cookies can be subject to CSRF or XSRF exploits. This answer used to say JWT was safer than cookies, because cookies were subject to CSRF attacks. But storing JWT in local storage is not safe either.

Which is more secure cookies or session?

Actually, technically cookies are more secure than sessions are. Since sessions are based on cookies they can only be as secure as cookies are, and almost always less secure than that. However, unless you have a very good implementation, sessions will be safer for you.

Does Facebook use sessions or JWT?

Other services have scaled successfully without JWT: This is also true (even Facebook doesn’t use JWTs). It is possible to scale well with opaque tokens, but it’s just much more difficult and expensive to do so (in terms of engineering costs as well as running costs).

Is session authentication secure?

Session security plays a key factor in building secure web applications. A web application is not secure unless it is protected from external attacks like XSS. According to OWASP (Open Web Application Security Project) Top 10, broken authentication is the second biggest risk to web application security.
