title: Why does tortoisegit never prompt me for a password (and fail because missing creds)?
body: <p>I have reinstalled tortoisegit twice now on my desktop, and for some reason it will never prompt me when working with my Google Code repo.  I have the changes commited, I just want to sync them out.  I am coming from tortoisesvn and tortoisehg where this is definitely possible.  I am trying to convert my repo to git, but running into issues with the program not prompting for any kind of password, and then failing to sync out because of permissions.</p>
