+<p>Android Studio provides the {@code finger} command, allowing you to simulate, and thus validate,
+fingerprint authentication for your app. After you set up your app to accept
+<a href="https://developer.android.com/preview/api-overview.html#authentication">fingerprint
+authentication</a>, your emulator or device should display the fingerprint authentication screen,
+as shown below. </p>

+
+<p>Open a terminal session, and telnet to the emulator. For example:</p>
+<pre>
+{@code telnet localhost 5554}
+</pre>
+
+<p>Enter the <code>finger</code> command to simulate finger touch and removal: </p>
+
+<ul>
+   <li><code>finger touch &lt;fingerprint-id&gt;</code> to simulate a finger touching the sensor</li>
+   <li><code>finger remove</code> to simulate finger removal </li>
+</ul>
+
+<p>Your app should respond as if a user touched, and then removed their finger from, the
+fingerprint sensor. </p>
