About JWT (JSON Web Tokens)
JWT is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. JWTs are commonly used for:
- Authentication and authorization
- Secure information exchange between client and server
- Single sign-on (SSO) systems
- API access tokens
- Stateless session management
Structure: A JWT consists of three parts separated by dots (.): Header.Payload.Signature
Security Note: This tool only decodes JWTs. It does not verify signatures. Never share secret keys or sensitive tokens publicly.
