 -->
+
+  <p>Users whose computers have a finterprint reader can use their fingerprints
+  instead of a password to log in. Fingerprint login
+  <link href="help:gnome-help#session-fingerprint">needs to be set up by the
+  user</link> before it can be used.</p>
+
+  <p>Fingerprint readers are not always reliable, so you may wish to disable
+  login using the reader for security reasons.</p>
+
+  <steps>
+    <title>Disable login using a fingerprint reader:</title>
+    <item>
+      <p>Create a <sys>local</sys> database for machine-wide settings in
+      <file>/etc/dconf/db/local.d/01-fingerprintreader</file>:
+      </p>
+<code># Specify the dconf path
+[org/gnome/login-screen]
+
+# Disable fingerprint reader
+enable-fingerprint-authentication="false"</code>
+    </item>
+    <item>
+      <p>Override the user's setting and prevent the user from changing it in
+      <file>/etc/dconf/db/local.d/locks/fingerprintreader</file>:</p>
+        <code># List the keys used to configure login
+/org/gnome/login-screen/enable-fingerprint-authentication</code>
+    </item>
+    <item>
+      <p>Update the system databases:</p>
