The plugin works fully without an API key, providing a comprehensive monitoring dashboard in your WordPress admin. The API key is only required if you want to access the monitoring data via REST API endpoints from external systems. ### What data does the plugin collect? The plugin collects: – Login attempt information (usernames, IP addresses, user agents, timestamps, success/failure status) – WordPress core version information– Plugin and theme information (names, versions, update availability) – File integrity checksums for WordPress core files – WooCommerce order information (if WooCommerce is active) No personal user data is collected beyond what’s necessary for monitoring purposes. ### Is the login data stored securely?

Yes, the plugin includes optional WooCommerce integration. If WooCommerce is active, the plugin will display recent orders in the dashboard and provide order information via the REST API. ### How does the file integrity check work? The file integrity check compares WordPress core files against official checksums provided by WordPress.org. It identifies files that have been modified, are missing, or are not part of the WordPress core. This helps detect unauthorized changes that could indicate security issues. ### Can I integrate this with external monitoring systems? Yes, the plugin provides REST API endpoints that can be accessed with a valid API key. This allows external monitoring systems to retrieve data about your WordPress site’s status, login attempts, and other monitoring information. ### Does this plugin work on multisite? The current version is designed for single-site WordPress installations. Multisite support may be added in future versions. ### What external services does this plugin use? This plugin connects to several external services to provide its functionality: – ip-api.com for IP geolocation (optional, can be disabled) – api.wordpress.org for WordPress core and plugin information (required) – api.github.com for enhanced plugin update analysis (automatic when available) All external service usage is documented in the “External Services” section. No personal data is transmitted except IP addresses for geolocation purposes. ### Can I disable external service connections? * IP geolocation can be disabled in plugin settings * WordPress.org API connections are essential for core functionality and cannot be disabled * GitHub API usage is automatic when repository information is available ### Is my data secure when using external services? Yes, the plugin only transmits minimal necessary data: – IP addresses to ip-api. com for geolocation – WordPress version and site URL to api.wordpress.org for update checks – Repository information to api.github.com for plugin analysis No personal user data, passwords, or sensitive information is transmitted. ## Reviews ![](https://secure.gravatar.com/avatar/fef40ceb8c34512f21f28aab0e9743d8d6665bc50b13153a630fc80615765676? s=60&d=retro&r=g) ### 󠀁[Excellent Monitoring Plugin!](https://wordpress.org/support/topic/excellent-monitoring-plugin/)󠁿 [piumi99](https://profiles.wordpress.org/piumineth/) November 3, 2025 I’ve been using SiteSignal across several of my WordPress websites, and it has been an outstanding tool.
