title: Can you use OpenID Connect without obtaining OAuth credentials?
body: <p>In <a href="https://developers.google.com/accounts/docs/OpenID#openid-connect" rel="nofollow">Google's OpenID Migration Guide</a>, for transitioning from OpenID 2.0 to OpenID Connect, step 1 is that I need to obtain OAuth credentials for my application.</p>
  
  <p>One thing I like about "regular" OpenID is that I can allow my users to authenticate from any IDP of their choosing.  Whether they use Google, Yahoo, or any other endpoint, as a developer I don't need to go through the trouble of manually obtaining OAuth credentials from each of those providers and configuring my application to support them.</p>
  
  <p>As providers discontinue support for traditional OpenID, is there a way for me to allow users to continue using their current IDPs without me having to go through each one and manually obtaining OAuth credentials?</p>
