Should I use JWT 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 better than 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 restful?
JWT (shortened from JSON Web Token) is the missing standardization for using tokens to authenticate on the web in general, not only for REST services. Currently, it is in draft status as RFC 7519. It is robust and can carry a lot of information, but is still simple to use even though its size is relatively small.
Are JWT safe?
It’s an encoded, URL-safe string that can contain an unlimited amount of data (unlike a cookie) and is cryptographically signed. When a server receives a JWT, it can guarantee the data it contains can be trusted because it’s signed by the source. No middleman can modify a JWT once it’s sent.
How are JWTs used to maintain session state?
JWTs provide a means of maintaining session state on the client in stead of doing it on the server. With server-side sessions you will either have to store the session identifier in a database, or else keep it in memory and make sure that the client always hits the same server.
Is it hard to invalidate a JWT session?
JWT sessions can sometimes be hard to invalidate. Trusting the client’s claim. These issues are shared by JWTs and other client-side session mechanisms alike. JWT, in particular, addresses the last of these.
What’s the difference between stateless JWT and stateful JWT?
Stateless JWT: A JWT token that contains the session data, encoded directly into the token. Stateful JWT: A JWT token that contains just a reference or ID for the session. The session data is stored server-side.
Which is better JWT tokens or session tokens?
This will more than likely be a much smaller table than the original session state table, so the lookups are still more efficient though. One other benefit of using JWT tokens is that it is reasonably easy to implement using libraries available in probably every language you can expect to have it.
