Can JWT be used 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 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”.

Is JWT better than session?

Session cookies take up very little bandwidth, whereas the bandwidth consumption will be higher in the JWT-based approach because the tokens tend to get bigger and you have the signature you have to send along for each follow up request; whereas if you have the session cookie, it's really small because its just the ...

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.

What is wrong with JWT?

JWT is just serialised, not encrypted. OAuth is not an API or a service: it's an open standard for authorization . OAuth is a standard set of steps for obtaining a token. There are 5 different flow patterns.

Should you use JWT or session based authentication in the Microservices environment?

The short answer is: None. A longer version is: I implemented JWTs for session management after reading this recommendation in the GraphQL docs: If you aren't familiar with any of these authentication mechanisms, we recommend using express-jwt because it's simple without sacrificing any future flexibility.

What is the difference between sessions and tokens?

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.

Can JWT token be stolen?

Why is JWT not secure?

JWT is a stateless session, so it does not need to be saved in a database in the server-side like cookies, it only exists in the client side. please notice that it is not encrypted it's just encoded which means you can use base64 decode and you will get the JSON object in clear.

Is JWT secure enough?

The general opinion is that they're good for being used as ID Tokens or Access Tokens and that they're secure - as the tokens are usually signed or even encrypted. You have to remember though, that JWT is not a protocol but merely a message format.

What websites use JWT?

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.

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 JWT authentication or authorization?

To authenticate a user, a client application must send a JSON Web Token (JWT) in the authorization header of the HTTP request to your backend API. API Gateway validates the token on behalf of your API, so you don't have to add any code in your API to process the authentication.

Where is JWT token stored on server?

A JWT needs to be stored in a safe place inside the user's browser. Any way,you shouldn't store a JWT in local storage (or session storage).
