title: Firebase V3 login in admin and debug mode
body: <p>In the new version of Firebase, (<a href="https://firebase.google.com/docs/reference/js/firebase.auth.Auth" rel="nofollow">https://firebase.google.com/docs/reference/js/firebase.auth.Auth</a>) I am looking for a method to set {admin:true,debug:true} in order to get admin access and debug mode to register all actions in the browser log. I know in the previous version that worked (<a href="https://www.firebase.com/docs/web/guide/login/custom.html#section-tokens-without-helpers" rel="nofollow">https://www.firebase.com/docs/web/guide/login/custom.html#section-tokens-without-helpers</a>), but in the new version I dont know if it is achieveable.</p>
