title: How long is the refresh token valid?
body: <p>On my localhost, I have authenticated my user and goten a Refresh Token and Access Token using <strong>Passportjs</strong>.</p>
  
  <p>I am using Google's Official Node.js library to get the Google Analytics data and it all seems to work fine.</p>
  
  <p>On this <a href="https://github.com/google/google-api-nodejs-client/issues/583#issuecomment-373794264" rel="nofollow noreferrer">GitHub issue</a>, Justin clearly mentions that the expiry is set by Google's APIs. </p>
  
  <p>How long is the refresh_token valid and at what time do i have to authorize myself again?</p>
