title: OpenID Connect delegation with Google now that they are deprecating their OpenID2 provider?
body: <p>For years I have used OpenID delegation to log in to Stack Overflow (among other sites) using my own URI as OpenID but having Google handle the authentication.  I use the technique described in <a href="https://stackoverflow.com/questions/2541526/delegate-openid-to-google-not-google-apps">this Stack Overflow question</a>; so, my custom OpenID <a href="http://tupelo-schneck.org/robert" rel="nofollow noreferrer">http://tupelo-schneck.org/robert</a> resolves to an HTML page containing this:</p>
  
  <pre><code>&lt;link href="https://www.google.com/accounts/o8/ud" rel="openid2.provider" /&gt;
  &lt;link href="https://www.google.com/profiles/schneck" rel="openid2.local_id" /&gt;  
  </code></pre>
  
  <p>Now, however, I have logged into Stack Overflow and had Google tell me "<strong>Important notice:</strong> OpenID2 for Google accounts is going away on April 20, 2015. <a href="https://support.google.com/accounts/answer/6135882" rel="nofollow noreferrer">Learn more</a>."  <a href="https://developers.google.com/accounts/docs/OpenID" rel="nofollow noreferrer">This page</a> explains that Google has deprecated OpenID 2.0 and developers should migrate their apps to OpenID Connect.</p>
  
  <p>Can I continue to use a custom URI for OpenID login, but delegate to Google's OpenID Connect provider for authentication?  How?</p>
