<h2>What is Omniauth?</h2>
<p>The web application landscape has changed drastically in the past few years. Most users login in to dozens, sometimes hundreds of services each day; sites are no longer silos unto themselves and cannot reasonably expect users to create a unique login and password for each service. This is where OmniAuth comes in.</p>
<p>OmniAuth is a library that standardizes multi-provider authentication for web applications. It was created to be powerful, secure, and flexible. Any developer can create strategies for OmniAuth that can authenticate users via disparate systems. OmniAuth strategies have been created for everything from Facebook to LDAP.</p>
<h2>Who’s Using OmniAuth?</h2>
<p>Hundreds of people are leveraging the advantages of super simple, secure authentication with OmniAuth in their applications. From event registration sites to online wholesale distribution stores, to online trading platforms and beyond, developers are relying on OmniAuth to streamline user authentication in their systems. </p>
<p>By default, OmniAuth will return auth information to the path
<code>/auth/:provider/callback</code> inside the Rack environment. In Sinatra,
for example, a callback might look something like this:</p>
<pre><codeclass="code"># Support both GET and POST for callbacks<br/>%w(get post).each do |method|<br/> send(method, "/auth/:provider/callback") do<br/> env['omniauth.auth'] # => OmniAuth::AuthHash<br/> end<br/>end</code></pre>
