Allow user to login with email address
On May 20, 2015 In Wordpress Tips and Tricks
We can easily enable wordpress users to login using email id. To do this, we can use the hook “authenticate”
Simply copy the following snippet in your plugin or functions.php file
add_filter('authenticate', 'allow_email_login', 20, 3);
function allow_email_login( $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 );
}
