title: Lost my github credentials; Now being prompted for username and getting an error
body: <p>I had to do a coding challenge last night that involved cloning a github repo. It was a hot mess and I frantically changed a bunch of settings trying to get it to work. Now, it appears that my personal account is broken as when I try to push code this morning, I get an authentication request and it fails.</p>
  <p>Here is what happens:</p>
  <pre><code>git push origin master
  (response from terminal)
  Username for 'https://github.com':(I enter my email)
  Password for '(my email)@github.com': (I enter my password)
  remote: Invalid username or password.
  </code></pre>
  <p>I deleted the ssh key last night and uploaded a new one. I am sure that has something to do with it. I am also not sure why it is adding the @github to my email when I enter it.</p>
