<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>

 * To send the magic link simultaneously from the management account.
 *
 * @param array  $emails  Multiple email addresses.
 * @param bool   true  Output notifications to the management screen immediately after sending.

<p><a href="https://www.cozmoslabs.com/add-ons/passwordless-login/" rel="nofollow ugc">Passwordless Login</a> is a modern way of loggin into your WordPress site without the use of a password.</p>
<p>Join the discussion here: <a href="https://www.cozmoslabs.com/31550-wordpress-passwordless-login/" rel="nofollow ugc">https://www.cozmoslabs.com/31550-wordpress-passwordless-login/</a></p>
<p>This is how it works:</p>
<ul>
<li>Instead of asking users for a password when they try to log in to your website, we simply ask them for their username or email</li>
<li>The plugin creates a temporary authorization token and saves it in a WordPress transient that expires after 10 minutes</li>
<li>Then we send the user an email with a link and the token</li>
<li>The user clicks the link and sends the authorization code to your server</li>
<li>The plugin then checks if the code is valid and creates the log in WordPress cookie, successfully authenticating the user.</li>
</ul>
<p>You can use the shortcode [passwordless-login] in a page or widget.</p>
<p>If you’re looking to create front-end user registration and profile forms we recommend <a href="https://www.cozmoslabs.com/wordpress-profile-builder/" rel="nofollow ugc">Profile Builder</a>.</p>
<p>NOTE:</p>
<p>Passwordless Authentication dose not replace the default login functionality in WordPress.</p>
