<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
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>.
