title: github, sourcetree getting unauthorized error
body: <p>im new to github and im using sourcetree for my git gui, ive been using it for a few days, but now lately im getting an error that says </p>
  
  <pre><code>remote: Invalid username or password.
  fatal: Authentication failed for 'https://github.com/Nosthertus/nodejs_Chat.git/'
  </code></pre>
  
  <p>also when i tried to make another registration to github returns with error</p>
  
  <pre><code>authorization failed
  </code></pre>
  
  <p>maybe its because i made a two-factor security, i thought on making a shh-key with github, but does not fix the problem, there has to be a way to make my gui connect to my github account without the login access, how do i fix this?</p>
