Inspect JWT headers and payload data in the browser.
Inspect JWT headers and payload data in the browser. It helps inspect JWT headers and payloads while debugging authentication, claims, expiry times, roles, and integration examples. Key capabilities on this page include header decode, payload decode, no server upload.
Use test tokens whenever possible. If a token is live, redact sensitive claims and remember that decoding does not verify the signature.
Paste a three-part JWT, decode it, review the header and payload JSON, then check claims such as issuer, audience, subject, and expiry in your own system.
A decoded token should have a valid JSON header and payload. Check timestamp claims carefully because they are often represented as Unix seconds.
