Frequently Asked Questions

What is a JWT?

A JSON Web Token (JWT) is a compact, URL-safe token format used to represent claims between two parties. It consists of a Base64-encoded header, payload, and signature separated by dots.

Is it safe to paste my JWT here?

ParseRed processes everything in your browser. Your token is never sent to any server. That said, avoid pasting production tokens with sensitive claims into any online tool as a best practice.
