<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>When configuring a <code>_auth</code> in routing, that configuration does not get used.<br>
It defaults to the provider ids defined in code.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>1. Create a route with custom _auth<br>
2. Try to use that auth provider.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>If _auth is configured on the custom route, use this instead of the default providers</p>
