<h3>Summary</h3>

    <p>This module provides authentication front-ends such as
    <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code> and <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>
    to authenticate users by looking up users in plain text password files.
    Similar functionality is provided by <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>.</p>

    <p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
    <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, this module is invoked via the
    <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or
    <code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code>
    with the <code>file</code> value.</p>

    <p>The <code class="directive">AuthUserFile</code> directive sets the name
    of a textual file containing the list of users and passwords for
    user authentication. <var>File-path</var> is the path to the user
    file. If it is not absolute, it is treated as relative to the
    <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>.</p>

    <p>Each line of the user file contains a username followed by
    a colon, followed by the encrypted password. If the same user
    ID is defined multiple times, <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> will
    use the first occurrence to verify the password.</p>

    <p>The encrypted password format depends on which authentication
    frontend (e.g. <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
    <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>) is being used.  See <a href="../misc/password_encryptions.html">Password Formats</a> for
    more information.</p>

    <p>For <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, use the utility <code class="program"><a href="../programs/htpasswd.html">htpasswd</a></code>
    which is installed as part of the binary distribution, or which
    can be found in <code>src/support</code>. See the
    <a href="../programs/htpasswd.html">man page</a> for more details.
    In short:</p>

    <p>Create a password file <code>Filename</code> with
    <code>username</code> as the initial ID. It will prompt for
    the password:</p>

    <div class="example"><p><code>
      htpasswd -c Filename username
    </code></p></div>

    <p>Add or modify <code>username2</code> in the password file
    <code>Filename</code>:</p>

    <div class="example"><p><code>
      htpasswd Filename username2
    </code></p></div>

    <p>Note that searching large text files is <em>very</em>
    inefficient; <code class="directive"><a href="../mod/mod_authn_dbm.html#authdbmuserfile">AuthDBMUserFile</a></code> should be used
    instead.</p>

    <p>For <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code>, use <code class="program"><a href="../programs/htdigest.html">htdigest</a></code>
    instead. Note that you cannot mix user data for Digest Authentication
    and Basic Authentication within the same file.</p>

    <div class="warning"><h3>Security</h3>
      <p>Make sure that the <code class="directive">AuthUserFile</code> is
      stored outside the document tree of the web-server. Do
      <strong>not</strong> put it in the directory that it protects.
      Otherwise, clients may be able to download the
      <code class="directive">AuthUserFile</code>.</p>
