title: Google API: How to increase access token expiration date?
body: <p>Google API expiration date is 1 hour, the problem is that I'm using the API in order allow users to use admin SDK features (List groups, add members to a group etc.) </p>
  
  <p>No one can do any of that in one hour, that would require users to login to their accounts multiple times per day to manage their groups. A 1 hour expiration date is good if you just want to use Google to authenticate users.</p>
  
  <p>How to increase that or is there any work around? Am I missing something?</p>
