How JWT Token Inspector Works
Parses JSON Web Tokens (JWT) into separate readable Header and Payload claims JSON views without transmitting sensitive authentication tokens.
Key Features
- Instant parsing of JWT Header and Claims payload.
- Auto-decodes token expiration (`exp`) and issued-at (`iat`) Unix timestamps.
Common Use Cases
- Debugging OAuth and OpenID Connect tokens, verifying user role scopes, and inspecting authentication claims.
