title: Securing API key on Github after being pushed
body: <p>I have unknowingly uploaded my api key for my app on Github and thus I deleted the api key from <a href="http://console.developer.google.com" rel="nofollow noreferrer">console.developer.google.com </a>  </p>
  
  <p>,Did it guarantee me that there will  not be any issue with that api key?</p>
  
  <p>Also ,I want help in how to remove that from all the commits in the project on Github.</p>
  
  <p>Any Suggestions are welcomed.</p>
