Frequently Asked Questions

What is a JWT?

A JSON Web Token (JWT) is a compact, URL-safe token used for securely transmitting information between parties. It consists of three parts: the header, the payload, and the signature. JWTs are often used for authentication and authorization in web applications.

Why can't I see my JWT token decoded properly?

If your JWT token is not decoding properly, it might be due to an invalid format or incorrect token structure. Ensure that your token has three parts separated by dots ('.') and is a valid JWT. If the issue persists, verify the token's integrity and encoding.

Is my JWT data stored or shared when using this tool?

No, your JWT data is not stored or shared. The tool processes your token locally on your device and does not send any data to external servers. However, we recommend not entering sensitive information into the tool.
