User login via E-mail in WordPress

Stanislav KhromovStanislav Khromov

Update 2017-04-03: This feature is included in core with WordPress versions 4.5 or later.

Here is a quick snippet to allow users on your site to sign in via their e-mail as well as their password.

Save it as a file in your plugins/ folder and activate it normally as a plugin.

<?php
/*
Plugin Name: Login with E-mail
Plugin URI: https://snippets.khromov.se/user-login-via-e-mail-in-wordpress/
Description: Lets users log in via their E-mail as well as their username
Version: 2014.07.03
Author: khromov

*/

add_filter('authenticate', function($user, $username, $password)
{
    if (is_email($username))
    {
        $user = get_user_by('email', $username);
        if($user)
            $username = $user->user_login;
    }
    return wp_authenticate_username_password(null, $username, $password);
}, 20, 3);

    Why make things so complicated? As for these aspects, the utilization of WordPress plugin is my first priority. Here, I highly recommend WP Email Login. After activation, you can just log out your dashboard and try to log in with your email address. I have shared the detailed steps at https://hostingreview360.com/how-to-allow-users-to-login-with-email-wordpress/. You can have a look as the reference.

      Hey Susan,

      The plugin you linked would work fine.

      Making your own plugin serves two purpose – understanding the inner workings and keeping track of the code that is running on your WP site. This isn’t always required but can be a worthwile exercise.

    WordPress core now support login via email. Not sure if this code is still needed.
