As web technologies continue to advance, so do the methods and protocols designed to secure them. The OAuth 2.0 and OpenID Connect protocols have significantly evolved in response to emerging security threats and the growing complexity of web applications. Traditional authentication methods, once effective, are now becoming outdated for modern Single Page Applications (SPAs), which face new security challenges. In this context, the Backend-For-Frontend (BFF) architectural pattern has emerged as a recommended solution for organizing interactions between SPAs and their backend systems, offering a more secure and manageable approach to authentication and session management. This article explores the BFF pattern in depth, demonstrating its practical application through a minimal solution implemented with .NET and React. By the end, you’ll have a clear understanding of how to leverage the BFF pattern to enhance the security and functionality of your web applications.
