是的，您可以添加authenticate 筛选以处理优先级高于默认wp\\U authenticate\\U email\\U password handler的电子邮件和无密码情况。e、 g.（未测试）

function wpse_380353_authenticate_email_no_password( $user, $email, $password ) {
    if ( is_wp_error( $user ) || ( $user instanceof WP_User ) ) {
        // Already handled by a higher-priority filter
        return $user;
    }

    if ( ! empty( $email ) && is_email( $email ) && empty( $password ) ) {
        // This is an email login with empty password
        $user = get_user_by( \'email\', $email );

        if ( $user && ! is_wp_error( $user ) ) {
            // TODO: Verify that the user is someone you\'d want to login without
            // a password. For now, let\'s reject anyone who can edit posts.
            if ( $user->has_cap( \'edit_posts\' ) ) {
                $error = new WP_Error();
                // TODO: localize the error message
                $error->add( \'empty_password\',
                    \'<strong>Error</strong>: This user requires a password.\' );
                return $error;
            }

            // We\'ll allow this user to login without a password.
            // Return the user object and the calling code will handle the login.
            return $user;
        }
        // else could not fetch the user by email address.
        // You\'ll probably now get a \'password field is empty\' error
        // from a later filter.
        // TODO: If you want a different error then generate it here.
    }

    return $user;
}

// Add an authenticate filter with a higher priority (= lower number) than
// wp_authenticate_email_password which has priority 20.
add_filter( \'authenticate\', \'wpse_380353_authenticate_email_no_password\', 10, 3 );
