Generate JWT tokens with issuer, subject, audience, expiration, and optional HS256 signing for local auth testing workflows.
Tool Interface
Functional explanation
Generates JWT samples for auth flow testing and token-shape iteration.
- Create reproducible token fixtures in QA.
- Test custom claim mapping in middleware.
- Simulate token payload variations rapidly.
How to use
Generate JWT tokens for local testing, auth debugging, and API integration work. This page is useful when you need a quick token builder with claim presets and optional HS256 signing.
- Set issuer, subject, audience, and expiration fields.
- Optionally choose HS256 and enter a signing secret.
- Add any custom claims you want in the payload.
- Generate the token and copy it into your app, API client, or test suite.
Example
Input
Claims={"sub":"user-1","role":"admin"}Output
Generated JWT test token
Use short expiry values in test environments.
Common mistakes
- Generating long-lived tokens for convenience.
- Skipping issuer and audience constraints in tests.
Output interpretation tips
- Decode generated token and validate claims immediately.
- Align algorithm choice with verifier configuration.
Security and privacy notes
- Do not distribute generated tokens with real scopes.
- Rotate any exposed key material immediately if leaked.
