OIDC and OAuth 2.0 – Tips from the trenches

Dominick Baier
Thursday March 12, 11:00 - 12:30
Short description

Building an API-based system with OIDC and OAuth 2.0 raises quite a few questions. In this session, we answer these questions using common patterns and anti-patterns derived from real-world scenarios.


There are typical architectural patterns around identity & access control for modern service-based applications. OIDC and OAuth 2.0 are the enablers for these architectures. Building such a system raises challenges and questions, such as which protocol flow to choose, how to design tokens, how to connect your various (new and old) clients to the token-based system, how to handle token lifetime management, etc.

In this session, we look at common patterns and anti-patterns on designing token-based systems.

Key takeaway

Advice on designing token-based authentication and authorization using OIDC and OAuth 2.0.
