Perfect, thanks for the explanation.

In this guide https://fusionauth.io/docs/v1/tech/core-concepts/authentication-authorization/ it is mentioned that you can set the option "Require registration" to true in order to avoid the generation of a jwt when a user is not registered in the given application.
But neither in the UI nor in the api documentation there is any optionlike this.

Our current problem is that one user can have multiple registrations but during the passwordless when we pass the application id a jwt should only be generated when the user is registered in this application.

Thanks in advance
