title: How to rotate Google oAuth client secret without downtime?
body: <p>I need to rotate the Google oAuth secret. For that I just need to go to the Google Cloud Platform Console > "APIs and Services" > "Credentials" > click on the client id under "OAuth 2.0 client IDs" > press the Reset Secret button.</p>
  
  <p>Then I need to take the newly generated secret and configure my servers to use it instead of the old one. Until I do this, my service will be inaccessible.</p>
  
  <p>How can I do this credential rotation and keep my service fully up through the operation?</p>
