Before adding Authentication as a Service, make sure you have added the initialization script tag.
If you have a Login or Sign in page, you can embed the Bread & Butter Authentication as a Service directly on the page, like you would with any other sign in option.
Once added, Authentication as a Service works just like the instant lead capture tool, except it is on the page, instead of hovering above.

This guide explains how to addAuthentication as a Service to your website.
<div /> element to the location on your page where you want the Bread & Butter 'Sign in' tool to appear.id attribute to the <div /> of "bb-signin-tool".<div id="bb-signin-tool" />

BreadButter.ui.signIn("bb-signin-tool");
