How to make private Debian Repo

Question

I'm reading this tutorial for creating a local repo.

Now, I want to make my repo private, so only if you provide a username/password then should you be able to access the Debian package.

How do I do that?

Answer 1

You configure your web server, FTP server, etc.—whatever you're using to share the repository with other machines—to require authentication.

The repository is just a bunch of files that your web server (typically) serves; there isn't really anything special about it. So you configure authentication the normal way for whichever web server you're using.

Debian Administration has a guide listing several methods.
