Agents need boundaries | Fotis Chantzis from OpenAI

Agents don't fit old identity models.

As OpenAI’s Agent Security Lead, Fotis Chantzis has a front-row seat to see how agents push identity systems beyond what they were built to control.

That’s where things start to fall apart and where most teams lose control.

In this episode, 1Password CTO Nancy Wang and 1Password VP of Engineering for Developer and AI, Jeff Malnick, ask Fotis where authentication starts to strain under the actions of agent identities, why secrets handling can get risky fast, and how teams should think about dynamic access controls.

In this episode:
Old identity models weren’t built for agents
The hardest security problems begin after access is granted
Long-running agents expose the limits of OAuth
Secrets remain one of the weakest links in agent design
How to stop agent overreach in real time with short-lived credentials and runtime boundaries
