TL;DR: AI agents need credentials to reach data and tools, but human-centric and static machine patterns often overscope access, weaken auditability, and complicate revocation, according to Descope. The governance problem is not just token handling, it is that current IAM assumptions break when agents act non-deterministically across multiple services in one workflow.
NHIMG editorial — based on content published by Descope: AI Agent Credential Management Best Practices
By the numbers:
- Only 13% of Model Context Protocol servers that begin development actually see deployment due to the difficulty of implementing auth requirements.
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: How should security teams implement AI agent credential management?
A: Security teams should issue short-lived, task-scoped credentials tied to the specific agent, tool, and resource involved, rather than sharing human sessions or static API keys.
Q: Why do AI agents create more credential risk than traditional workloads?
A: AI agents create more credential risk because they do not follow one fixed access path.
Q: What breaks when agents inherit a human user's active session?
A: When agents inherit a human user's active session, the agent gets more permission than the task usually needs, and the organisation loses a clean boundary between delegation and execution.
Practitioner guidance
- Issue task-scoped agent identities Assign each agent a distinct identity with permissions tied to the specific task, tool, and resource set, rather than reusing a shared service account or user session.
- Separate authorisation from resource access Place token issuance and policy enforcement behind a dedicated authorisation layer so the agent server validates access but does not also become the policy decision point.
- Eliminate standing access from agent workflows Use short-lived credentials that expire when the work completes, and remove long-lived keys from environment variables, config files, and shared deployment images.

AI agent credential management exposes an identity boundary problem, not just a token hygiene problem. The central issue is that agents do not behave like traditional NHIs and do not authenticate like humans. They need credentials that can follow non-deterministic runtime decisions without turning every tool into a standing trust grant. Practitioners should treat credential design as the control plane for agent behaviour, not as a back-office secret storage task.
A few things that frame the scale:
- 98% of companies plan to deploy even more AI agents within the next 12 months, despite documented rogue behaviour in 80% of current deployments, according to AI Agents: The New Attack Surface report.
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials, according to AI Agents: The New Attack Surface report.
A question worth separating out:
Q: Who is accountable when an AI agent misuses valid credentials?
A: Accountability should follow both the delegating user and the system that issued the credential, because valid access does not remove governance responsibility. Organisations need logs that show which agent acted, under whose delegation, with which scopes, and against which downstream service so compliance and investigation can trace the event cleanly.
