title: How can I prevent OAuth server from remembering user?
body: <p>I have a webapp which asks user several questions and store answers. User logs in via OAuth using external provider, then I get user ID information from external SSO server. </p>
  
  <p>I need my app to be used by several users at the same computer, so every time the form is submitted, I need to log out the user. I can do it easily in my app, but then I redirect user to OAuth server again. OAuth server remembers user, so it gives the code of previously logged user right away. I want users to log in again at OAuth server though, but how can I do it? Is it possible to ask OAuth server not to remember the user that had logged in previously?</p>
