How it works
This tool builds a JWT from a header and payload and signs it using a selected algorithm. It’s useful for local development and debugging.
Example
Header:
{"alg":"HS256","typ":"JWT"}
Payload:
{"sub":"123","role":"admin"}FAQ
Should I generate real production tokens here?
Avoid using real production secrets in untrusted environments. Use secure server-side tooling for production keys.
Which claims are common in JWT payloads?
Common claims include sub, iss, aud, iat, and exp depending on your authentication design.
