WPMU User Synchronization 1.1.6
Wordpress Plugins WPMU DEV 4.8 (3.4K reviews)
WPMU User Synchronization is a WordPress plugin developed by WPMU, the team behind a suite of WordPress tools. The plugin solves a problem that administrators of multiple WordPress sites deal with constantly: keeping user accounts in step with one another. When you run several installations—perhaps a network of blogs, a parent site with child sites, or a group of separate but related projects—your users often need to exist everywhere. This plugin syncs user accounts and transfers complete profiles across those WordPress installations without recreating each account by hand. Instead of copying names, emails, and roles one at a time, you can push that information from one site to another and keep future changes aligned. The result is a single source of truth for your user data, while each site remains an independent installation running its own WordPress core. That distinction matters because full multisite networks share one database, while this plugin handles the trickier case of separate installations that still need to talk.
Security is the first concern when user data starts traveling between servers, and the plugin addresses this with security keys that protect user information while syncing. These keys work as an authentication layer between the sites involved, so the transfer of profiles, account metadata, and access details does not happen in the clear or through unverified channels. Each sync operation carries the key, allowing the receiving installation to confirm that the data actually came from the trusted source. For anyone managing WordPress root logins, administrator accounts, or contributor profiles, this is the difference between a convenient sync tool and one that is safe to run in production. The plugin also gives you control over which user data moves and how the receiving site treats it. You are not locked into a single all-or-nothing transfer model. You can decide what is synchronized, how tightly the sites remain connected after the initial copy, and what happens when a user changes their profile information on the source installation.

Two features stand out for real-world administration. The first is the option to allow duplicate users for backward compatibility. This matters when you already have some users on the receiving site, or when two installations developed separate account lists over the years. Rather than forcing a merge that could break existing posts, assignments, or plugin records, you can keep duplicates and let the sync bring new accounts across without destroying what is already there. The second feature is the ability to ban a user from a specific sub-site. This gives site administrators fine-grained control over the network. A user might remain active on the main site or on other sub-sites, but you can block their access to one particular installation where their presence causes problems. That kind of per-site moderation is hard to achieve with standard WordPress user tools, which either allow or deny at the network level. Here you get that control without the plugin removing the account globally.
The plugin comes as a standard .zip installation file, the same package you would receive from the original developer, ready to be uploaded through the WordPress plugin installer or extracted into your plugins directory. Once activated, all the synchronization settings live inside the WordPress admin area, so there is no separate panel or external service to manage. Site administrators can map which installations share data, configure the security keys, and review what the plugin synchronizes. For anyone running several independent WordPress installations that need to share identity data, this tool removes the repetitive manual work of maintaining user records in multiple places. It does not turn your sites into a single multisite network, and it does not force you to give up per-site independence. It simply keeps user accounts moving between the installations that need them, with protection and control built in.
