Real-world failures

API key breaches we prevent.

Every year, API keys leak from places everyone trusted. These companies had security teams, audits, and budgets. The keys were still exposed.
2026
Vercel AI Agent Credential Breach
A compromised AI agent with long-lived API keys exposed production credentials across connected services. Persistent secrets stored alongside agent code turned a single breach into full lateral access.
✓ With Authgent, agents never hold keys. Credentials are isolated and single-use — a compromised agent doesn’t expose your keys.
2025
AI Agent Tool Poisoning Attacks
Malicious third-party tools injected into agent workflows harvested API keys from environment variables during execution. Agents passed live credentials through untrusted tool chains.
✓ With Authgent, tools never see credentials. Your agent gets results without credentials entering the tool chain.
2024
Mass AI API Key Exposure
Over 12,000 OpenAI and cloud API keys were found leaked on GitHub in a single year. Developers hardcoded agent credentials in repos, .env files, and notebook configs.
✓ With Authgent, your codebase has zero credentials in it, even in a full source leak.
2023
CircleCI Secret Exfiltration
Attackers compromised a CircleCI engineer’s laptop and used it to steal customer secrets — API tokens, service credentials, signing keys — stored in the CI platform.
✓ With Authgent, stolen tokens are already burned. An attacker gets expired, one-time keys — worthless.
Three operations

How AI agent credential management works.

01 · REGISTERISOLATED

Your key is created inside a locked vault.

When you register an agent, a key is generated inside a zero-custody vault — we don’t have access to it. You get a login token to control your agent. The actual key stays locked inside. Always.

$ authgent register --name my-agent
→ credential generated in secured hardware…
✓ agent_id: d72caa47-d8d5
✓ token: agt_9f2c…b81a
02 · CALLZERO CUSTODY

Your agent gets the result. The key stays contained.

Your agent requests the action and gets the result. The credential is handled separately — your code never touches it.

agent.call(
  provider="stripe",
  method="POST",
  path="/v1/charges")
✓ 200 · via authgent
03 · REVOKEINSTANT

Something wrong? Kill the key instantly.

One command and the key is destroyed. The old credential stops working immediately. Like changing the locks — the old key is dead, nothing works with it anymore. You can create a new agent in seconds.

$ authgent revoke
→ destroying credential…
✓ credential destroyed

Threat model · public

Security threat model for AI agent authentication.

Protected

✓
Someone hacks your AI agent
Intercepted credentials are already expired by the time an attacker tries to use them.
✓
Someone hacks our database
They find scrambled data they can’t use. Your credentials aren’t stored in a way that can be extracted.
✓
Someone hacks our servers
They find metadata and expired credentials — nothing usable. No real passwords, no live credentials. Re-register and you’re back in minutes.
✓
A rogue employee
Our own team sees encrypted data — we designed it so we don’t have access to your credentials.
✓
Someone intercepts the API calls
The key doesn’t travel over your network. Your server handles responses, not credentials. An attacker sniffing your traffic sees nothing because the key was never there.
✓
Someone reads your code or config
Your codebase has no credentials in it — no .env files, no config files, no API keys in your environment.
✓
DDoS or service outage
Your vault keeps working independently. No dependency on our infrastructure for ongoing operations.

Out of scope

×
Physically tampering with the vault
Physical attacks against the credential isolation layer. This is outside the threat model we address.
×
Controlling what your agent decides to do
We limit what your agent is allowed to do — but we don't control its reasoning. That's your responsibility.
×
Securing your own services
We protect the keys and make the call. But your own APIs still need their own security — we can't do that for you.
×
Filtering what your agent says
We control which APIs your agent can access and revoke credentials instantly — but we don’t read or filter its messages.

Questions

Frequently asked questions.

How does Authgent secure my AI agent’s API keys?

Your API keys stay in a zero-custody vault — we don’t have access to them. Your agent gets the result without ever handling the key directly.

What is zero-custody credential management?

Zero-custody means the service that stores your credentials cannot access or extract them. Unlike a traditional password manager where the operator could theoretically read your secrets, Authgent is designed so that we can’t access your credentials. Even we can’t read what’s stored.

What happens if my AI agent is compromised?

Intercepted credentials are already expired. You can also revoke all access instantly with a single command.

Which AI frameworks and providers does Authgent support?

Authgent works with any API — OpenAI, Anthropic, Stripe, GitHub, AWS, and any service that uses API keys or tokens. It’s framework-agnostic: use it with LangChain, CrewAI, AutoGPT, or your own custom agent code.

How is Authgent different from a secrets manager like Vault or AWS Secrets Manager?

Traditional secrets managers store and retrieve secrets — your application still handles the raw key. With Authgent, your application doesn’t handle the key at all. The credential stays contained — your code works with results, not secrets.
