Security Disclaimer
warningImportant Notice
TokenDecode is an informational developer utility, not a security auditing or authentication authority. Do not rely on our tools for production security validation.
Decoding ≠ Verification
When you use the JWT Decoder or JWT Inspector to parse a token, the tool only translates the Base64URL-encoded strings into readable JSON. Decoding a JWT does not verify its cryptographic authenticity. A token that decodes cleanly may still be forged, expired, or signed with an incorrect key. You must always verify token signatures using robust cryptographic libraries on your backend servers.
Generated Tokens are Not Secure
The Token Generator utility creates unsigned test tokens (`alg: none`) with an empty signature segment. Generating an unsigned test token does not create a production authentication token. These mock tokens are strictly intended for local frontend development or isolated unit testing where signature validation is explicitly disabled. They provide no cryptographic integrity.
Independent Review Required
All outputs from TokenDecode tools—whether formatted payloads, encoded strings, or decoded structures—should be independently reviewed and verified before being utilized in any production environment or security-critical application.
