Frequently Asked Questions
What is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. JWTs are encoded as a JSON object that is digitally signed using JSON Web Signature (JWS).
How do I use this JWT reader?
Simply paste your JWT into the input field and our tool automatically decodes the header, payload, and signature. All decoding happens client-side for security.
