Frequently Asked Questions
What is a JWT?▼
A JSON Web Token (JWT) is a compact, URL-safe token format used for authentication. It consists of three Base64-encoded parts: header, payload, and signature, separated by dots.
Is it safe to paste my JWT here?▼
Yes — this tool runs entirely in your browser. Your token is never sent to any server. However, never share JWTs publicly as they may contain sensitive information.
