OAuth Token Viewer

New

Decode and inspect OAuth 2.0 access tokens, Bearer tokens, and ID tokens. If the token is a JWT, the header and payload are decoded. For opaque tokens, the tool identifies the token type and provides basic inspection. Displays token metadata like scopes, expiry, issuer, and audience. Useful for debugging OAuth flows, understanding token structure, and verifying claims during development.

Frequently Asked Questions

What is the difference between an access token and an ID token?
