About LCK cloud Connector

From the official readme · v1.0.8

Description

Securely turn your existing WordPress content into “Members Only” pages. This plugin provides professional access control and member management.

“LCK cloud Connector” is an official plugin designed to integrate advanced membership features into your WordPress site without complex coding.

What is LCK cloud?
LCK cloud is a membership site building system provided as a cloud service (SaaS) in Japan. Signing up gives you a working membership site with member registration, login, member management and group-based permissions, and it is available on a free plan with no expiration date. This plugin connects that membership system to the WordPress site you already have.

Key Roles of This Plugin:
You can easily set “access restrictions” for existing pages, posts, and categories. By implementing a system where only logged-in users can access specific content, you can properly control the range of information disclosure.

Security by Data Isolation:
Unlike standard membership plugins, it does not store sensitive member data (names, passwords, payment info, etc.) in your WordPress database. By isolating and managing data within the secure LCK cloud environment, you can minimize security risks for your website.

Features and Solutions:
* Membership Management: Seamless integration and stable operation with LCK cloud.
* Access Control: “Members Only” settings for individual pages or entire categories.
* Flexible Access Rules: Supports wildcard (*) for dynamic path matching.
* Automatic Redirect: Automatically guides non-logged-in users to the secure login screen.
* No-Code Design: Admin interface that eliminates the need to edit WordPress functions.php.
* High Reliability: Provided by a registered “Telecommunications Business Operator (Notification No. E-02-04640)” with the Kinki Bureau of Telecommunications in Japan.

Ideal for corporate portals, member-only media, and internal document sharing sites. It supports smooth website operation as a secure “Membership Management WordPress” solution.

日本語説明

WordPressサイトに閲覧制限とセキュアな会員管理機能を。既存のコンテンツを「ログイン限定」へ切り替えるためのプラグインです。

「LCK cloud Connector」は、既存のWordPressサイトを活用して、安全な会員制サイトを構築するための公式コネクタです。

【LCK cloudとは】
LCK cloudは、会員制サイト作成システムをクラウドで提供しているサービスです。登録するだけで、会員登録・ログイン・会員管理・会員グループごとの権限設定を備えた会員制サイトが用意され、使用期限のない無料版から利用できます。本プラグインは、そのLCK cloudの会員機能を、お手持ちのWordPressサイトから利用できるようにするものです。

【本プラグインの主な役割】
特別なカスタマイズを行うことなく、固定ページ、投稿、カテゴリーに対して「閲覧制限」を設定できます。 特定のユーザーのみがログインしてアクセスできる仕組みを導入することで、情報公開の範囲を適切に制御することが可能です。

【データ隔離によるセキュリティ設計】
会員の個人データ(名前、パスワード、決済情報等)をWordPress側のデータベース内に保持しない設計を採用しています。 国内の専用環境(LCK cloud)でデータを隔離して一元管理する仕組みにより、サイト運営におけるセキュリティのリスクを最小限に抑えられます。

【主な機能と運用ニーズへの対応】
* 会員管理 WordPress 連携: LCK cloudとの同期による、安定したメンバーシップ運用。
* 閲覧制限・アクセス制御: ページやカテゴリー単位での「ログイン限定」設定機能。
* 認証画面への誘導: 未ログイン者が制限ページにアクセスした際の自動リダイレクト。
* ノーコード設計: functions.php などのプログラム編集をせず、管理画面から設定可能。
* 国内データセンターの利用: 総務省近畿総合通信局届出済みの電気通信事業者(届出番号 E-02-04640)による提供・運営。

法人向けのポータルサイト、会員限定のメディア、社内用資料共有サイトなど、高い信頼性と分かりやすい「会員サイトの作り方」を必要とする環境に適しています。 セキュリティと利便性の両立を目的とした「会員管理 WordPress」のソリューションとして、円滑なサイト運営を支援します。
