This generator creates unsigned tokens (`alg: none`) for local testing only.
What This Tool Does
Generate unsigned test tokens to prototype claims and auth middleware behavior locally.
Use it to inspect or transform input quickly, then carry validated output into code, tests, or API requests.
Common Use Cases
- Mock auth state in local development.
- Generate expiring token fixtures for tests.
- Prototype role-based claims quickly.
Common Pitfalls
- Unsigned tokens must never be used in production.
- Incorrect claim timestamps can produce immediate auth failures.
FAQ
Can I use generated tokens in production?
No, use real signing keys and verification flows.
Why include exp/iat claims?
They model realistic token validity windows.
Does this tool send data to a backend?
Most tools process input client-side in your browser unless explicitly noted.
