Agentic Access: OAuth Gets You In. Zero Trust Keeps You Safe

This talk is confirmed. The time of the talk will be announced soon.

The recording will be published after editing. Multipass and Full ticket holders have early access.

AI agents are no longer experimental. Developers are already using them to query APIs, modify content, and chain services using emerging protocols like MCP (Model Context Protocol). The latest MCP specification introduces modern OAuth 2.1 authentication and support for Resource Indicators (RFC 8707), strengthening identity in agent-based systems.

But authentication alone does not guarantee control. Once an agent is logged in, how do you govern what it is allowed to do? Without proper authorization controls, agents can access far more resources than they need, creating significant security risks.

This talk explores how to apply Zero Trust principles to agent workflows by combining open identity protocols with policy-aware infrastructure. You will see a demo of an MCP client interacting with a secured MCP server behind Pomerium, an open source identity-aware proxy that brings fine-grained access control to agent interactions. Beyond basic authentication, Pomerium evaluates per-request policies based on identity, route, and context, and can audit and block specific tool calls within the MCP protocol. It can even manage OAuth flows to upstream tools like Notion or Reddit, so agents never handle raw access tokens.

What you will learn:

- Why OAuth is necessary but not sufficient for agent security
- How to apply Zero Trust to developer tools and AI workflows
- A practical example of securing MCP servers with open source infrastructure

As AI agents become part of real-world developer workflows, open standards and secure defaults are key to building trust without adding friction. These security patterns apply beyond just AI systems to any automated tooling that needs controlled access to APIs and services.

The talk discusses the importance of supply chain security in the open source ecosystem, highlighting the risks of relying on open source code without proper code review. It explores the trend of supply chain attacks and the need for a new approach to detect and block malicious dependencies. The talk also introduces Socket, a tool that assesses the security of packages and provides automation and analysis to protect against malware and supply chain attacks. It emphasizes the need to prioritize security in software development and offers insights into potential solutions such as realms and Deno's command line flags.

The State of Passwordless Auth on the Web

Phil Nash

Passwords are terrible and easily hacked, with most people not using password managers. The credential management API and autocomplete attribute can improve user experience and security. Two-factor authentication enhances security but regresses user experience. Passkeys offer a seamless and secure login experience, but browser support may be limited. Recommendations include detecting Passkey support and offering fallbacks to passwords and two-factor authentication.

Lucas Estevão, a Principal UI Engineer and Technical Manager at Avenue Code, discusses how to implement Content Security Policy (CSP) with Next.js to enhance website security. He explains that CSP is a security layer that protects against cross-site scripting and data injection attacks by restricting browser functionality. The talk covers adding CSP to an XJS application using meta tags or headers, and demonstrates the use of the 'nonce' attribute for allowing inline scripts securely. Estevão also highlights the importance of using content security reports to identify and improve application security.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool. There are multiple alternatives that are much better than passwords to identify and authenticate your users - including SSO, SAML, OAuth, Magic Links, One-Time Passwords, and Authenticator Apps.
While addressing security aspects and avoiding common pitfalls, we will enhance a full-stack JS application (Node.js backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session securely for subsequent client requests, validating / refreshing sessions- Basic Authorization - extracting and validating claims from the session token JWT and handling authorization in backend flows
At the end of the workshop, we will also touch other approaches of authentication implementation with Descope - using frontend or backend SDKs.

In this workshop we will go through all the aspects and stages when integrating your project into Code Quality and Security Ecosystem. We will take a simple web-application as a starting point and create a CI pipeline triggering code quality monitoring for it. We will do a full development cycle starting from coding in the IDE and opening a Pull Request and I will show you how you can control the quality at those stages. At the end of the workshop you will be ready to enable such integration for your own projects.
