Windows 10: How to set the proxy with username and password to download an archive from github using...

I have a csproj, in which there is common.props pointing out an URL which should download an archive. But it fails due to Proxy Authentication

What is a "proxy username and password"

Ok, I know the question seems rather dumb but please allow me.
I know what the concept of a proxy is. I am not asking "what is a proxy"
I use a proxy here, and I have set it to say "proxy_ip" and "port" in the Proxy settings

Then I read something like this
answer to cloning Github with proxy

and I am what? What "username"? what "password"? I did not know proxys have anything to do with usernames or passwords... or does it

What is this?
