Official connector plugin to securely link WordPress and LCK cloud, enabling professional membership sites.

== Description ==

"LCK cloud Connector" is a plugin that adopts the "SaaS Bridge Architecture" to fuse the flexible design of WordPress with the robust security of a SaaS-based membership management system.

**Why LCK cloud?**
Unlike standard WordPress plugins, it does not store member data or payment information within the WordPress database. This minimizes the risk of critical customer data leakage even if vulnerabilities are found in the WordPress core.

**Key Features:**
* Flexible access control by page or category.
* Automatic redirect function to the LCK cloud authentication server.
* Admin interface that eliminates the need to edit WordPress functions.php.
* Integration with a secure member management environment of telecommunications carrier quality.

**Reliability and Identity:**
This plugin is developed and provided by LCK cloud, a registered "Telecommunications Business Operator (Notification No. E-02-04640)" with the Kinki Bureau of Telecommunications of the Ministry of Internal Affairs and Communications in Japan. We use domestic data centers to ensure high reliability suitable for corporate use.
