If self._get_new_password() is always called, is self.password still needed?

I think this is useful in case of 401 where url credentials are not (directly) available (like url forwarding by the server to a specific file). Also, to be honest, as this is my first PR here, I've tried to minimize the scope of my change. Feel free to improve it if anything. thank you

Yeah, you’re right, handle_401 writes to this dict. With this patch, self.passwords will serve as a fallback when self._get_new_credentials() returns (None, None).

The logic change looks correct to me, although some refactors would be best; we can get to that later. First you’ll need to fix the tests.

Thank you for the feedback. I will fix the tests soon.

thank you for your helpful review @uranusjr

Changes approved and tests are passing. Is it ready to be merged ?

That is a very interesting feature. It would help us too
And drastically improve the usage of git repository in pip.

Any idea of when it will be merged ?

Thank you

Any idea of when it will be merged ?

Whenever one of the maintainers (who are almost exclusively volunteers) come around to taking a look at this.

Thanks for the PR @snook92 and for the detailed review @uranusjr! ^>^
