Tips for Best Results
Ensure the JWT has three parts separated by dots (header.payload.signature)
Provide a secret for HMAC algorithms (e.g., HS256) or a public key for RSA/ECDSA (e.g., RS256)
Check the verification status to confirm signature validity
Copy or download the decoded header and payload as JSON
