How to have the authentication service on HTTPS instead of HTTP?

[VantageKR]

By default, the IDS4 authentication service runs over HTTP: how can we have that over HTTPS please? Since a user has to obtain the JWT token through the IDS4 service, if it runs on HTTP it means that the user will be sending the username and password over HTTP as well as receiving the JWT token over unencrypted HTTP. Is there a simple way to enable HTTPS here. As for the actual API, that is nicely by default HTTPS, so no issues here! Thanks in advance.
