THE OUTCOME
What credential model should AI agents use?
Use short-lived, purpose-bound access instead of durable shared secrets wherever the system supports it — a stolen credential with a narrow expiry limits the useful attack window.
Use this guide to: Review short-lived agent credentials, least privilege, expiry and revocation.
CORE MODEL
What are the four core ideas to know before acting?
Four ideas anchor the guide: short life reduces exposure, scope binds purpose, issuance needs identity, and revocation still matters.
Scope binds purpose
Credential permissions should identify resource, action, tenant and sometimes amount.
Issuance needs identity
The broker must authenticate the requesting agent or controller before minting access.
Revocation still matters
Compromise response cannot rely only on waiting for expiry.
ACTION CHECKLIST
What are the six steps of the review process?
The six steps run from inventorying every agent secret through moving issuance behind an authenticated broker, setting minimal scopes and TTL, avoiding raw credentials in logs, rotating signing and issuer keys, and correlating issuance with every use.
- Inventory every agent secret
- Move issuance behind an authenticated broker
- Set minimal scopes and TTL
- Avoid logging raw credentials
- Rotate signing and issuer keys
- Correlate issuance with every use
