<p><code>actix-identity</code> can be used to track identity of a user across multiple requests. It is built
on top of HTTP sessions, via <a href="https://docs.rs/actix-session"><code>actix-session</code></a>.</p>
<h2 id="getting-started"><a href="#getting-started">Getting started</a></h2>
<p>To start using identity management in your Actix Web application you must register
<a href="struct.IdentityMiddleware.html" title="IdentityMiddleware"><code>IdentityMiddleware</code></a> and <code>SessionMiddleware</code> as middleware on your <code>App</code>:</p>

<p>By default, <code>actix-identity</code> does not automatically log out users. You can change this behaviour
by customising the configuration for <a href="struct.IdentityMiddleware.html" title="IdentityMiddleware"><code>IdentityMiddleware</code></a> via <a href="struct.IdentityMiddleware.html#method.builder" title="IdentityMiddleware::builder"><code>IdentityMiddleware::builder</code></a>.</p>
<p>In particular, you can automatically log out users who:</p>
