Can you steal JWT?

Can you steal JWT?

Yes! If a JWT is stolen, then the thief can can keep using the JWT. An API that accepts JWTs does an independent verification without depending on the JWT source so the API server has no way of knowing if this was a stolen token! This is why JWTs have an expiry value.

How do I use JWT for authorization?

Arguably one of the largest use cases for JWT is authorization. We can generate a JWT token in the backend that is specific to a user, pass this JWT token to the frontend, and then our frontend can send this token alongside requests to access protected API routes. JWT tokens can be given an expiration time.

What is JWT validation?

The Validate JWT policy enables you to secure access to your APIs by using JWT validation. For example, when an input request that contains a JWT in the header is received, the Validate JWT policy extracts the token, verifies, and decrypts (if appropriate) the signature, and validates the claim.

What are the uses of JWT?

JWT claims can typically be used to pass identity of authenticated users between an identity provider and a service provider, or any other type of claims as required by business processes. JWT relies on other JSON-based standards: JSON Web Signature and JSON Web Encryption.

Is a JWT usable as a CSRF token?

You could use a JWT as a CSRF token, but it would be needlessly complicated: a CSRF token doesn’t need to contain any claims, or be encrypted or signed. There is probably a misunderstanding about what JWT or CSRF tokens are used for (I was confused at first too). The JWT is an access token, used for authentication.

What is JWT, JSON Web Token for?

JSON Web Token (JWT, sometimes pronounced /dʒɒt/) is a JSON-based open standard (RFC 7519) for creating access tokens that assert some number of claims. For example, a server could generate a token that has the claim “logged in as admin” and provide that to a client.
