Modern applications increasingly need to connect with multiple internal and external APIs, bringing forth the challenge of managing authentication and authorization securely. OAuth 2.0 has emerged as the industry standard for addressing this challenge, enabling users to grant permissions without exposing their credentials.

In this session, we will provide a clear and accessible introduction to OAuth 2.0 and OpenID Connect, demystifying their terminology and demonstrating practical applications in real-world scenarios. We will explore the most commonly used flows—including Client Credentials Flow, Authorization Code Flow, Device Code Flow, and Resource Owner Password Flow—and discuss the contexts in which each is recommended.

Additionally, we will highlight advanced approaches such as Reference Tokens, a more secure alternative to traditional access tokens, and CIBA (Client-Initiated Backchannel Authentication), which enables background authentication in scenarios with minimal user interaction.

By the end of this session, you will gain practical insights into implementing these protocols to build more secure applications, enhance data protection, and streamline authentication and authorization management in your systems.
