About JWT Generator
The JWT Generator lets you create JSON Web Tokens instantly for development, debugging, and testing authentication systems. Customize the header, payload, and secret key to generate a signed token using common algorithms such as HS256.
Why use this tool?
- •Quickly prototype and test JWT-based authentication flows
- •Inspect how claims are structured inside a token
- •Debug APIs that require Bearer tokens without spinning up a full auth server
- •Learn how JWT signing works in a safe, sandboxed environment
Important: This tool runs entirely in your browser. No tokens or secrets are ever sent to a server. Use it for development and testing only — never share production secret keys.
