How to configure local IPM registry authorization?

I'm working on my first (!) IPM module and I'm a little puzzled with the registry authorization.

I have a working local registry (I hope!) and the module is loaded (with load-command) to the namespace.

Now publish-command fails because of missing authorization. I have set nothing authorization related myself and I'm lost how the authorization should be configured. All the material I have read so far seems to ignore that and only mentions one have to authenticate ...

Here's the command output:
