Now you see me, now you don't: Ephemeral Auth and AI agents

Agents are popping up everywhere: tiny bots spinning up for a task, then dying off. They shouldn’t carry long-lived credentials any more than you carry a master key everywhere you go. What if each agent got a just-for-this-mission credential—scoped, temporary, context-aware, and gone when its task ends? That’s ephemeral authentication. 

In this episode, F5's Lori MacVittie, Joel Moses, and special guest Bill Church dig into why traditional IAM (OAuth tokens, persistent keys) fails in agentic worlds. They’ll show how ephemeral auth can reduce blast radius, prevent credential replay, and force “least privilege in the moment.” Then they walk through how it might be built: token issuance on mission start, embedded attestation, automatic revocation, and scope tunneling per action. And yeah, there are tradeoffs—latency, credential churn, throttling limits. Listen in for the best path forward.
