<h4>Thanks</h4>
<ul>
<li>This plugin is a modified version of <a href="https://wordpress.org/plugins/passwordless-login/" rel="ugc">Passwordless Login</a>.</li>
<li>The main changes are the addition of various filter hooks and the addition of the following action hooks.</li>
</ul>
<h4>Action hook</h4>
<ul>
<li>This is for sending bulk e-mails with a magic link for login to multiple accounts from the management screen.</li>
<li>When using this action hook, the URL of the page where the shortcode [magic_login] is placed should be specified in the filter hook ‘magic_login_mail_url’.</li>
</ul>
