What is a .jwt file?

A JWT (JSON Web Token) is a compact, URL-safe token made of three base64url-encoded parts — a header, a payload of claims, and a signature — separated by dots. It is widely used to carry authentication and authorisation claims between services.

How to use this file

Use a sample JWT to test token decoding, claim extraction, and signature verification. Never use an example token's secret in production.
