About

Decode A JWT And See Its Security Issues

Paste a JWT or an OAuth redirect URL into the popup. The extension decodes header, payload, and signature locally and runs security checks against the claims.

WHAT IT DOES

- Decodes JWT header, payload, and signature using standard base64url decoding in the popup
- Extracts the token from an OAuth redirect URL if you paste one (access_token, id_token, or token in the URL fragment or query)
- Runs checks against the claims: alg = none detection, HMAC warning, expiration status, issued-at display, audience presence, issuer presence, subject presence

HOW IT WORKS

1. Click the icon
2. Paste a JWT or OAuth redirect URL
3. See the decoded fields and security checks

PRIVACY

Decoding happens entirely in the popup's JavaScript context. Tokens are never transmitted. No storage, no telemetry.
