AuthBridge Cross-Site Sign-On is a plugin that creates a unified login system for multiple, independent websites. It is designed for administrators who manage a network of distinct sites and want to improve the user experience by removing repetitive login barriers.

• Centralized Authentication: Users authenticate through a single, designated login site. Once logged in, they are automatically recognized on all other connected sites without needing separate accounts or passwords.
• Independent Site Management: Each website in the network remains a separate installation with its own content, users, and admin area. The plugin only synchronizes login status, preserving individual site control and data separation.
• Simplified User Experience: Eliminates the frustration of managing multiple logins. Users can move freely between your connected sites, which can increase engagement and reduce support requests for password resets.
• Cookie-Based Session Sharing: The system works by sharing secure session cookies between sites. This method allows for near-instant recognition without complex server-side user database merging.
• Flexible Configuration: Administrators can choose which sites act as the central login hub and which sites are clients, allowing for tailored network architectures to fit specific project needs.
