JWT content is decoded locally in your browser. Treat this as structure analysis only; signature validation requires the issuer key.
No JWT has been provided yet.
Weak JWT validation can allow session abuse, privilege confusion, stale-token access, or acceptance of forged tokens if the server trusts unverified claims.
Validate JWT signatures server-side using the issuer public key or shared secret, enforce expected alg, iss, aud, exp and nbf claims, and never authorize users based only on decoded client-side payloads.
Test expired, wrong-audience, wrong-issuer and tampered-signature tokens and confirm the server rejects them.
Decoded header and payload will appear here.
