Paste a JWT token and inspect every part instantly. Great for debugging auth, role claims, and expiration.
Paste token
Bearer prefix is accepted and stripped automatically.
Inspect header and payload
Focus on alg, sub, aud, exp, and custom claims.
Check expiry and signature
The tool warns if token is expired, expiring soon, or missing signature.
JWT is a three-part token format commonly used for authentication.
The three parts are header, payload, and signature separated by dots.
Check exp first, then verify aud and iss match backend expectations.
If signature is empty, the token is often truncated or malformed.
