title: Using OAuth2 on a shared browser/environment
body: <p>I have a single-page application that allows using OAuth2 to authenticate users. This SPA is also used in a common area where multiple people share the same physical desktop and the same local desktop user and thus the same browser profile (similar to a kiosk environment).</p>
  <p>The problem is that when a user logs in using OAuth2 that is linked to say their personal Google account, another user could come along later and have access to the previous users Google account since they are still logged in after authenticating via OAuth2.</p>
  <p>Local application user accounts can be auto-logged out by the SPA itself, but it can't auto-logout a user from their Google account.</p>
  <p>Is there a solution for this? I am unsure if the answer is with OAuth2, the shared browser, or the SPA.</p>
