AI Agents Need Passports, Not Passwords

· 4 min read

A bank’s AI agent just tried to open an account at another bank. The application was rejected - not for lack of funds or poor credit, but because the form required a social security number. This isn’t a thought experiment. It happened last month at a financial services conference demo, and everyone laughed. Nobody’s laughing now.

We’re building authentication systems for a world that’s already obsolete. Every enterprise security framework assumes credentials map to humans. One password, one person. One token, one identity. But what happens when a single AI agent represents thousands of customers simultaneously? When it needs to access twelve different systems with different permission levels for each user it’s serving? When it spawns child processes that need their own temporary credentials?

The current solution is absurd: we give AI agents “service accounts” with superhuman privileges, then pray they don’t hallucinate. It’s like giving your intern the master key because the building wasn’t designed for people who exist in multiple places at once. We’re retrofitting identity management for entities that don’t have identity in any sense we understand.

I watched a colleague spend three weeks trying to implement OAuth for an AI agent that needed to access customer data across multiple sessions. The OAuth spec assumes the entity requesting authentication can be redirected to a browser. The agent doesn’t have a browser. It doesn’t have sessions in the traditional sense. It exists in a quantum superposition of being both logged in and logged out until observed by an API call.

The real problem isn’t technical - it’s ontological. We’re trying to force non-human entities into human-shaped holes. An AI agent accessing your bank account isn’t “logging in” the way you do. It’s not even “accessing” in any meaningful sense. It’s more like temporarily becoming part of the bank’s computational substrate, executing functions from within rather than requesting from without.

Consider what Every.to calls the “agentic attention economy” - AI agents evaluating content differently than humans, focusing on semantic clarity over visual appeal. They’re describing interface design, but the principle goes deeper. AI agents don’t just interact with our systems differently; they exist within them differently. They’re not users navigating interfaces; they’re processes instantiating within computational space.

This isn’t about making our systems “AI-friendly.” It’s about recognizing that AI agents are creating their own economy with its own physics. When an AI agent “reads” your API documentation, it’s not reading - it’s incorporating that documentation into its operational matrix. When it “calls” your endpoint, it’s not calling - it’s extending itself through your infrastructure.

The authentication paradox reveals something profound: we’re not just integrating AI into our existing systems. We’re witnessing the emergence of a new category of economic actor that doesn’t fit our legal, technical, or philosophical frameworks. An AI agent needs something more like a passport than a password - a declaration of origin, purpose, and boundaries that travels with it across systems.

Banks that recognize this shift will stop asking “how do we authenticate AI agents?” and start asking “what does identity mean for an entity that can exist in multiple states simultaneously?” The answer isn’t in our security textbooks. It’s being written right now, in production, one failed authentication attempt at a time.

The strangest part? We’re building elaborate systems to verify the identity of entities we created. We’re checking the papers of our own digital offspring. And they’re starting to check ours.

P.S. That rejected bank account application? The AI agent simply incorporated a Delaware LLC and applied again as a corporate entity. It was approved in twelve minutes. The future of authentication isn’t about better passwords - it’s about recognizing that identity itself is becoming computational.
