How to use the JWT Inspector?

What is a JWT Inspector?

A JWT Inspector allows you to examine the structure and contents of a JSON Web Token. It separates the token into its header, payload, and signature components for easier inspection.

How do I inspect a JWT?

Simply paste your JWT into the inspector and start the inspection. The tool decodes the readable parts of the token and displays its contents in a clear and structured format.

What information can I see in a JWT?

A JWT contains a header, a payload, and a signature. The header describes the token, while the payload contains claims and other information included in the token.

Can I inspect an expired JWT?

Yes. You can inspect an expired JWT to view its structure and payload. However, an expired token may no longer be accepted by the application or API that issued it.

Is my JWT uploaded to a server?

No. CodeLiqo’s JWT Inspector processes your token directly in your browser. Your JWT does not need to be uploaded to a remote server for inspection, helping keep your data on your device.
