How do I use JWT securely?

Issuing a token

1. Always sign the token.
2. Use strong cryptography.
3. Set expiration date and unique identifier.
4. Set the issuer and audience.
5. Don’t include sensitive data unless you encrypt the payload.
6. Don’t accept unsigned tokens.
7. Validate header claims.
8. Always validate issuer and audience.

How do you secure a JWT token in the application?

JWT Security Best Practices

3. What algorithms to use.
4. When to validate the token.
5. Always check the issuer.
6. Always check the audience.
7. Make sure tokens are used as intended.
8. Dealing with expiration, issued time and clock skew.

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.
