WordPress custom login form without password

If you want to create a login process in WordPress without any password, this tutorial will be helpful for you. In this tutorial I will show you how to login into WordPress with username or email only. Let’s get started!

Step 1. You need a front-end user login form. Please copy the below code and then paste where you want to show the form.

// Form
<form autocomplete="off" method="post">
    <div class="form-group">
        <input id="userlog" name="userlog" type="text" placeholder="<?php echo esc_attr__('Username/email', 'theme-domain'); ?>" class="form-control" required="required">

    <input type="hidden" name="action" value="my_login_action" />

    <button type="submit"><?php echo esc_html__('Login', 'theme-domain'); ?></button>  

Step 2. Then paste the below code in your theme’s functions.php file or your site-specific plugin.

// Calling ob_start function
function theme_domain_output_buffer() {
add_action('init', 'theme_domain_output_buffer');

// Login
add_action('init', function(){

    // Return if not the login request
    if( !isset( $_POST['action'] ) || $_POST['action'] !== 'my_login_action' )
	$username = $_POST['userlog'];
	if ( ! $result ) {
	    $result = get_user_by( 'email', $username ); // user email
	if ( ! $result ) {
	    $result = get_user_by('login', $username ); // user name
	if ( !is_wp_error($result) ){
	    wp_redirect( home_url( '/' ) );

That’s it!

Happy coding. Thanks!
