How should teams govern AWS Bedrock API keys in GenAI workflows?

TL;DR: AWS Bedrock now supports API keys that simplify access to generative AI models but also expand the non-human identity surface, with short-term keys valid up to 12 hours and long-term keys able to run without expiration, according to AWS. That makes lifecycle control, discovery, and rotation the real governance problem.

NHIMG editorial — based on research published by Entro Security.

By the numbers:

• AWS states that short-term Bedrock API keys can be valid for up to 12 hours, reducing the lifetime of exposed credentials.

Questions worth separating out

Q: How should teams govern API keys for AI model access?

A: Treat them as non-human identities with the same controls you apply to service account secrets.

Q: When do short-lived AI credentials still create risk?

A: Short-lived credentials still create risk when discovery is weak, logs are incomplete, or the token is copied into places that persist longer than the credential itself.

Q: What is the difference between IAM roles and direct API keys for AI workloads?

A: IAM roles rely on controlled assumption of access and usually fit better into policy, review, and revocation workflows.

Practitioner guidance

• Classify Bedrock keys as governed NHIs Assign every API key an owner, a business purpose, an expiry date, and a review cadence so it enters the same control plane as other secrets and service identities.
• Block unmanaged key distribution paths Scan repositories, logs, build systems, Slack, and Jira for embedded Bedrock keys, then remove or quarantine any instance that lacks approved lifecycle controls.
• Prefer time-bounded access by policy Allow short-term keys where direct model access is unavoidable and require explicit approval for any key that can be created without expiration.

The practical response is to unify AI access with the rest of the secrets estate, because separate processes create separate blind spots?
