<desc>Prevent the user from being able to log in using a fingerprint
 scanner.</desc>
 </info>

<title>Disallow login using a fingerprint</title>

Users with a fingerprint scanner 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.

Fingerprint readers are not always reliable, so you may wish to disable
 login using the reader for security reasons.

<steps>
 <title>Disable login using a fingerprint reader:</title>
 <include href="dconf-snippets.xml"
 xpointer="xpointer(/*/*[@xml:id='dconf-profile-user'])"
 xmlns="http://www.w3.org/2001/XInclude"/>
 <include href="dconf-snippets.xml"
 xpointer="xpointer(/*/*[@xml:id='dconf-profile-user-dir'])"
 xmlns="http://www.w3.org/2001/XInclude"/>
 <item>
 Create the key file
 <file>/etc/dconf/db/local.d/00-login</file> to provide
 information for the <sys>local</sys> database.
 <listing>
 <title><file>/etc/dconf/db/local.d/00-login</file></title>
<code>
# Specify the dconf path
[org/gnome/login-screen]

# Disable fingerprint reader
enable-fingerprint-authentication=false
</code>
 </listing>
 </item>
 <item>
 To prevent the user from overriding these settings, create the file
 <file>/etc/dconf/db/local.d/locks/login</file> with the following
 content:
 <listing>
 <title><file>/etc/dconf/db/local.d/locks/fingerprintreader</file></title>
<code>
# List the keys used to configure login
/org/gnome/login-screen/enable-fingerprint-authentication
</code>
 </listing>
 </item>
 <include href="dconf-snippets.xml"
 xpointer="xpointer(/*/*[@xml:id='dconf-update'])"
 xmlns="http://www.w3.org/2001/XInclude"/>
 <include href="dconf-snippets.xml"
 xpointer="xpointer(/*/*[@xml:id='dconf-logoutin'])"
 xmlns="http://www.w3.org/2001/XInclude"/>
 </steps>
