title: Which user does Eclipse login need for push to Github?
body: <p>I want to use GitHub and Eclipse for my Python project, but I have difficulties with it. Detailed steps are below, this is the short version of the question: I managed to create a repository in GitHub, import it in Eclipse, connect a project to it and make local commits. Now, when I want to push my branch, I have to fill out a username and password. I have tried my GitHub username+password, my SSH key emailaddress + password and my computer username+password, but none of these seem to work. Which username is required in this screen? Is there something else that I am forgetting?</p>
  
  <p>Steps taken so far:</p>
  
  <p>1) Create a GitHub repository

  <p>2) Generate a SSH key for my computer, following <a href="https://help.github.com/articles/generating-ssh-keys/" rel="nofollow noreferrer">https://help.github.com/articles/generating-ssh-keys/</a>

  <p>3) Import the repository in Eclipse
  File -> Import -> Projects from Git -> Clone URI
  In Authentication, I fill in my GitHub username and password

  <p>4) In PyDev Package Explorer, Team -> Share project
  I use the repository just added

  <p>5) Without doing anything to the project, I choose Team -> Commit
  I commit and push both files

  <p>6) Now, it asks me for a login user and password
