WPMU DEV: WORDPRESS USER SYNC

WPMU DEV WORDPRESS USER SYNC is a WordPress plugin that streamlines cross-site user management by synchronizing accounts across multiple WordPress installs from a single master list. Instead of creating or updating users separately on each site, it keeps profiles, passwords, roles, and email addresses aligned across connected subsites.

Useful for teams running several sites without relying on WordPress Multisite, it supports one-time registration and consistent login credentials wherever the user is connected. With secure site linking and simple configuration, it helps reduce onboarding time while maintaining continuity when users are transferred or disconnected.

Main Features

• Master list user synchronization — Connect multiple WordPress installations to a central set of user accounts.
• Profile, password, role & email sharing — Keeps key identity fields consistent across all linked sites.
• Secure site linking keys — Protects the connection between master and subsite during sync.
• Fast one-click configuration — Requires a master list URL and a security key to get started.
• Synchronize-overwrite mode — Enforces identical master list matches for consistent results.
• Backward compatibility via duplicates — Supports existing password behavior using optional duplicates on connected sites.
• Subsite list & activity manager — Provides visibility into connected subsites and synchronization activity.
• User ban for a specific subsite — Prevents deleted users from repopulating on selected sites.
• Uninstall database cleanup — Wipes plugin database artefacts when the plugin is removed.

Benefits

• Faster onboarding — Users register once on the master list and become usable across connected sites quickly.
• Consistent login experience — Shared credentials reduce confusion and support seamless access across properties.
• Reduced admin workload — Automated profile and account updates eliminate repetitive manual user management.
• Improved data accuracy — Overwrite synchronization helps prevent mismatched roles, emails, or passwords.
