Auth Token
- Paste Token: Enter your encoded JSON Web Token (JWT) into the input box.
- View Decoded Data: The tool automatically splits and decodes the Header and Payload.
- Inspect Claims: Read the decoded JSON to verify claims like
exp(expiration) orsub(subject). - Copy: Use the copy buttons to grab the decoded JSON for debugging or documentation.
Debugging authentication issues often requires peeking inside JWTs. Our tool makes this process seamless and secure. By decoding tokens entirely in your browser, we ensure your sensitive session data is never exposed to external servers, giving you a safe environment to troubleshoot login flows and API authorizations.
