Third-Party Service

This plugin connects to the wp-admin.online service to provide centralized WordPress site management. The following data is sent to the wp-admin.online API (https://wp-admin.online/api/v1):
* WordPress version and PHP version
* List of installed plugins and themes (names, versions, active status, and on a multisite network whether they are network-activated or network-enabled)
* On a multisite network, once a network administrator has allowed network reporting for the connection, the list of sites (name, address, status, active theme and active plugins of each)
* Administrator usernames and display names (for one-click login)

Data is transmitted over HTTPS and authenticated using HMAC signatures. No data is sent until you configure your API credentials.
