Frequently Asked Questions
What is a JWT token?
JWT (JSON Web Token) is a compact, URL-safe token format used for securely transmitting information between parties. It consists of three parts: header, payload, and signature.
Does this tool verify the JWT signature?
No. This tool only decodes the JWT to show the header and payload. It does not verify the signature or validate the token. Use this for debugging and inspection only.
Is my JWT token secure?
This tool processes JWTs entirely in your browser. Your tokens are never sent to any server. However, never share your JWT tokens publicly as they may contain sensitive information.
