Credential Narrowing
Credential narrowing is the process of deriving a new credential from a broader parent credential with a reduced set of permissions—limiting the derived credential to only the access required for a specific task or tool call.
Why this matters for AI agents
Credential narrowing is how least privilege is operationalized in agent systems. Without it, agents must use parent credentials with all their associated permissions.
How AgntID relates
AgntID performs credential narrowing at the enforcement layer—broad service account or OAuth credentials are narrowed per task so agents receive minimally-scoped credentials at execution time.
The static IAM gap
Credential narrowing at the tool-call level is not a native capability of IAM or secrets management platforms. It requires a runtime enforcement and credential brokering layer.
