A new architectural pattern for plugin authentication is gaining attention: chain-of-delegation. Instead of a monolithic authentication module, this design allows multiple providers to claim authentication in a prioritized chain. The system supports exclusive, OR, and mixed authentication modes, with pluggable strategies for termination and final verdict. This approach is particularly relevant for plugin frameworks where different plugins may require different authentication mechanisms. The architecture includes two API layers: a simple layer for common cases and an advanced layer for complex scenarios. This pattern reduces coupling and increases flexibility, making it easier to extend authentication without modifying core logic. For developers building plugin-based systems, this offers a robust alternative to traditional authentication models.
This article introduces a plugin authentication architecture using a chain-of-delegation pattern, where providers claim authentication in priority order. It offers a flexible, pluggable approach for exclusive, OR, and mixed authentication scenarios. This is a significant architectural pattern for plugin-based systems.
