FAQ

Is the generated JWT production-ready?

The generated JWT is structurally valid and suitable for development and testing. For production, use proper key management, secure signing with RS256/ES256, and server-side libraries like jsonwebtoken or jose.

What claims should I include?

Standard claims: sub (subject/user ID), iss (issuer), exp (expiration timestamp), iat (issued at), aud (audience). Add custom claims for roles, permissions, or application-specific data.
