Hi @simonj ,

I am not sure if you can generate Auth0 JWT token. Since you cannot access Auth0 private key. Posting you article on the same.

> I need to create a JWT token (RS256) and I tried [jwt.io](http://jwt.io) but since the private key isn’t accessible as stated here: [If we can not get the private key when use choose RSA256 as JWT signature algorithm](https://community.auth0.com/t/if-we-can-not-get-the-private-key-when-use-choose-rsa256-as-jwt-signature-algorithm/22554) Does Auth0 have a straightforward way to just create a JWT token for my payload, instead of building an actual application with SDK integrated for authorization? Thanks!
