Fake JWT Generator

Generate fake JWT tokens for testing and development. Useful for simulating authentication in applications without needing a real server.

What is a JWT?

JWT (JSON Web Token) is an open standard (RFC 7519) that defines a compact and self-contained way to transmit information between parties as a JSON object. This generator creates fake JWT tokens for testing and development purposes.

⚠️ Important Warning

The tokens generated by this tool are FAKE and should not be used in production or for real authentication. They are useful only for testing, development, and demonstrations. The signature is randomly generated and is not valid.

Use Cases:

  • API development testing
  • Authentication simulation in applications
  • Demonstrations and prototypes
  • Integration testing
  • Learning about JWT structure
  • Debugging authentication systems

JWT Structure

A JWT is composed of three parts separated by dots:

  • Header: Contains the token type (JWT) and the signing algorithm
  • Payload: Contains the claims - data about the user and metadata
  • Signature: Signature to verify the token integrity (randomly generated in this generator)
