title: Source Tree account switch
body: <p>I am trying to push to a repository under user account 'starhunter1' using source tree. Since initially while installing source tree i might have used 'starhunter2' account, hence while trying to push i am receiving a permission error. How can i switch the account to that of 'starhunter1'. I tried uninstalling and re-installing source tree but it does not help and still throws the below error. </p>
  
  <pre><code>git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin v1:v1
  remote: Permission to starhunter1/TestJenkins.git denied to starhunter2.
  fatal: unable to access 'https://github.com/starhunter1/TestJenkins.git/': The requested URL returned error: 403
  Pushing to https://github.com/starhunter1/TestJenkins.git
  Completed with errors, see above.
