Is JWT better than session?

JWT (JSON Web token) approach:

Since userId is got by decrypting the JWT token, no DB call is required to get userId, so somewhat faster that session approach. Servers can be scaled separately, without the need share sessionDB. This makes the JWT approach a great option for micro-services architecture.

Should I use JWT for session?

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.

Does JWT replace session?

Thank you so much for your detailed answer, JWT could not fully replace session, so a lot of the merit of JWT(like CDN, stateless etc) would only work for Authentication server, not the business server, unless we use Redis to save session data as Spring recommended.

Does Google use sessions or JWT?

Google does not use JWTs for user sessions in the browser. They use regular cookie sessions. JWTs are used purely as Single Sign On transports so that your login session on one server or host can be transferred to a session on another server or host.

Which is better session or token?

The main difference is session-based authentication of the connection stores the authentication details. The session method makes the server store most of the details, while in the case of the token-based one the client stores them.

Session vs Token Authentication in 100 Seconds

Is JWT authentication good?

Information Exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be sure that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn't been tampered with.

Why is session based authentication bad?

Because in session based authentication, you do not reveal user password (in browser for example). Since it's just a random id, one cannot get information from it.

Does Facebook use JWT?

It provides an entry point: “/auth/facebook” that redirects to FBs and proceeds to the authentication. After that it acquires the AccessToken for the logged user and creates a JWT Token that returns to the client.

Does Instagram use JWT?

It seems that instagram doesn't use jwt (Json web token) in it's authentication system. As you know jwt is a more secure way for user authentication instead of session based systems. In jwt token is stored in the database and with each request, we send the token in our localStorage to serve to validate that.

Can JWT token be stolen?

What to Do if JWT Token is Stolen? There could be nothing worse than getting a JWT token stolen, as it's like providing a license to bypass all the layers of security to an attacker for exploiting sensitive information.

Is session and JWT same?

The JWT tokens are sometimes referred to as “Bearer Tokens” since all the information about the user i.e. “bearer” is contained within the token. In case of the session cookie based approach, the sessionId does not contain any userId information, but is a random string generated and signed by the “secret key”.

What is wrong with JWT?

Drawbacks. There are major drawbacks to using JWT. First, it's a complicated standard and users are prone to get the settings wrong. If the settings are wrong, in the worst case it could mean that anyone can generate valid JWTs and impersonate anyone else.

Is JWT token enough?

JSON Web Tokens (JWT) is a JSON-encoded representation of a claim or claims that can be transferred between two parties. Though it's a very popular technology, JWT authentication comes with its share of controversy. Some say you should never use it.

Does JWT put your web app at risk?

No they are not. Also the same applies to sessions, sessions should be refreshed, too. To clean up, your application may null out the session or remove the persisted value from the data store. The result is the same; no more session.

Is session based 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. These malicious scripts are designed to gain access to sensitive data in web applications, including cookies, as they act as a key to store session tokens.

Why should we use JWT instead of cookie based authentication?

The better solution (Modern approach) JWT is a token based stateless authentication mechanism. Since it is a client-side based stateless session, server doesn't have to completely rely on a datastore(database) to save session information.

What companies use JWT?

Are discord tokens JWT?

But keep in mind that the Discord example you have shown is no JWT and JWT has some overhead because it has a header and it uses JSON. As jps says, that example from Discord is not a JWT. It's just a token which happens to look a bit similar to a JWT.

Is JWT an OAuth?

Basically, JWT is a token format. OAuth is an authorization protocol that can use JWT as a token. OAuth uses server-side and client-side storage. If you want to do real logout you must go with OAuth2.

How does JWT token expire?

The API returns a short-lived token (JWT), which expires in 15 minutes, and in HTTP cookies, the refresh token expires in 7 days. JWT is currently used for accessing secure ways on API, whereas a refresh token generates another new JWT access token when it expires or even before.

Where JWT token is stored?

Most people tend to store their JWTs in the local storage of the web browser. This tactic leaves your applications open to an attack called XSS. We will only discuss XSS in the JWT context, you can find more about it here.

What is the max size of JWT token?

By default, AM rejects any JWT that expands to more than 32 KiB (32768 bytes), and throws an exception with a message similar to JWT payload decompressed to larger than maximum allowed size .

Are sessions secure?

PHP sessions are only secure as your application makes them. PHP sessions will give the user a pseudorandom string ("session ID") for them to identify themselves with, but if that string is intercepted by an attacker, the attacker can pretend to be that user.

Is it okay to share a session ID via a URL?

Yes, sharing a session ID is okay, as it is going only to the intended user. Ans : An application must not share a session ID via a URL.
