What would happen if a refreshed JWT was requested with a JWT that had already expired?

On every request, check the JWT’s expiration date (which is self-contained in the JWT). If the JWT expired, the request is rejected, and the client is forced to generate a new JWT. When a “refresh JWT” request is received, validate against the database record. Do not generate a new JWT if validation fails.

Why is JWT bad?

An unexpiring JWT can become a security risk. You are also trusting the token signature cannot be compromised. This can happen if you are using weak encryption, encryption that becomes vulnerable in the future, or having the the private keys compromised. This vulnerability doesn’t exist with sessions.

Is JWT an OAuth?

So the real difference is that JWT is just a token format, OAuth 2.0 is a protocol (that may use a JWT as a token format or access token which is a bearer token.). OpenID connect mostly use JWT as a token format.

Can localStorage be hacked?

2 Answers. Local storage is bound to the domain, so in regular case the user cannot change it on any other domain or on localhost. It is also bound per user/browser, i.e. no third party has access to ones local storage. Nevertheless local storage is in the end a file on the user’s file system and may be hacked.

Is local storage more secure than cookies?

While cookies do have a “secure” attribute that you can set, that does not protect the cookie in transit from the application to the browser. So it’s better than nothing but far from secure. Local storage, being a client-side only technology doesn’t know or care if you use HTTP or HTTPS.

Why do we use JWT token?

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.

Is it safe to store JWT in Redux?

To answer your question, it can be a secure place to store JWT, but it depends on how you are thinking of persisting the JWT. … If you are using a SPA frontend, as well as having refresh tokens implemented, you could save that refresh token in a httpOnly cookie, and just get a new JWT when the user starts a new session.

Can JWT be used for sessions?

JWT doesn’t have a benefit over using “sessions” per se. JWTs provide a means of maintaining session state on the client instead of doing it on the server. … Moving the session to the client means that you remove the dependency on a server-side session, but it imposes its own set of challenges.

Does JWT prevent CSRF?

This prevents the browser from sending the cookie if an unsecured communication channel is used (i.e. not https). When setting the JWT cookie, you should also set an HTTP header which will also contain your generated CSRF token. … Then it should compare it against the CSRF token that’s in the request header.

How long should a JWT last?

around 15 minutesThis is why JWTs have an expiry value. And these values are kept short. Common practice is to keep it around 15 minutes, so that any leaked JWTs will cease to be valid fairly quickly. But also, make sure that JWTs don’t get leaked.

Where should I store JWT?

A JWT needs to be stored in a safe place inside the user’s browser. If you store it inside localStorage, it’s accessible by any script inside your page (which is as bad as it sounds, as an XSS attack can let an external attacker get access to the token). Don’t store it in local storage (or session storage).

What to do if JWT token is expired?

The most common solution is to reduce the duration of the JWT and revoke the refresh token so that the user can’t generate a new JWT. With this setup, the JWT’s expiration duration is set to something short (5-10 minutes) and the refresh token is set to something long (2 weeks or 2 months).
