Frequently Asked Questions

Common questions about HarmonyUser Sync – Sync Users & Customers Across Multiple Sites

A: Communication is secured using WordPress's built-in Application Passwords. When you add a target site, the plugin generates a specific, revocable password for the API. Your main administrator password is used only once for this generation and is never stored. The 2.0 version adds IP & URL whitelist features for enhanced security.

A: Yes, HarmonyUser Sync is designed to synchronize standard WordPress users as well as WooCommerce customers.

A: The plugin includes an intelligent loop prevention mechanism. When a site receives a sync request and prepares to forward it to its own targets, it excludes the original sender and any sites already in the path list, effectively stopping loops.

A: Yes, in the plugin's Settings page, you can select which user roles should be eligible for synchronization.

A: Every sync attempt (success or failure) is logged in detail under HarmonyUser Sync > Sync Logs. You can review the logs to diagnose any issues.

A: Yes, the Manual Sync tool allows you to select specific users and target sites for on-demand synchronization.

A: Every sync request carries a list of sites that have already been part of the current sync chain. When a site receives a request, it will not forward it to any site already in that list, which effectively breaks the loop. Q: What is the difference between "Prohibit Sync Propagation" and "Reject Incoming Modifications"? (New in 2.0) A: They control syncs at a user-level but in opposite directions. Prohibit Sync Propagation is an outgoing control. It stops a user's changes on the source site from being sent out to other sites. Reject Incoming Modifications is an incoming control. It protects a user on a target site from being changed by a sync coming from another site. Q: How does the Whitelist feature work? (New in 2.0) A: The whitelist feature ensures that your site only accepts sync requests from pre-approved URLs and IP addresses. You can manage the whitelist through the "User Sync > Whitelist" menu and enable/disable the feature in the main settings. Q: Can I use my own Application Passwords? (New in 2.0) A: Yes, version 2.0 introduces flexible authentication methods. You can either let the plugin generate Application Passwords automatically or manually enter existing ones for enhanced security control.
