    <title>DESCRIPTION</title>

    <para>
      The <emphasis>pam_faillock.so</emphasis> module maintains a list of
      failed authentication attempts per user during a specified interval
      and locks the account in case there were more than
      <replaceable>deny</replaceable> consecutive failed authentications.
      It stores the failure records into per-user files in the tally
      directory.
    </para>
    <para>
      The <command>faillock</command> command is an application which
      can be used to examine and modify the contents of the
      the tally files. It can display the recent failed authentication
      attempts of the <replaceable>username</replaceable> or clear the tally
      files of all or individual <replaceable>usernames</replaceable>.
