title: Google API refresh token limit
body: <p>I'm developing an application wherein I need to access multiple google calendars. All these calendars come from different users. And right now I am using OAuth2 for the syncing. But as I understand it, I can only generate 25 refresh tokens per client ID. </p>
  
  <pre><code>Note: Save refresh tokens in secure long-term storage and continue to use 
  them as long as they remain valid. Limits apply to the number of refresh 
  tokens that are issued per client-user combination, and per user across all clients, 
  and these limits are different. If your application requests enough refresh tokens 
  to go over one of the limits, older refresh tokens stop working.
  </code></pre>
  
  <p>As advised, I am keeping the refresh tokens in my DB. But my problem is, what if I get more clients who would want to sync their calendar? Is there any way to overlook the limit? Of course there isn't. What I have in mind right now is just to create more client IDs. Any advise?</p>
