title: SHA 1 Hash key is same for all application?
body: <p>I have integrated Google login in my Android application before one month. Now I am planning to launch another application with different package name. I am trying to implement Google login in this application too. </p>
  
  <p>When I have generated and pasted SHA 1 to google and its giving error like below</p>
  
  <pre><code>Duplicate fingerprint
  The fingerprint you specified is already used by an Android OAuth2 client ID in this project or another project
  </code></pre>
  
  <p>I want know that SHA 1 is same for all project in same machine even We change package name in application ?</p>
  
  <p>What is solution for use Google login in another application ? I am confused because Google ask package name with Google Auth. I have marked that in new package also Google signin working fine but it will cause issue in future ?</p>
