TL;DR: AI agents are increasingly being authenticated with OAuth 2.0 and OpenID Connect, but the real issue is not login mechanics, it is whether scoped tokens, rotation, auditability, and tenant isolation can contain machine-speed behaviour, according to WorkOS. Access review processes assume access persists long enough to be reviewed; autonomous actors can chain actions faster than governance cycles can observe them.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “The best providers for authenticating AI agents via OAuth and OIDC in 2025”.
Key questions
Q: What breaks when AI agents inherit user OAuth sessions too broadly?
A: Broad inheritance collapses the boundary between human intent and machine execution.
Q: Why do AI agents increase the risk of overpermissioning?
A: AI agents increase that risk because teams often expand scopes to unblock early use cases, then keep those permissions because the original need is hard to prove or remove.
Q: How do you know if agent authentication is actually working?
A: Agent authentication is working when each agent has a unique identity, token scope matches the approved task, actions are fully attributable, and revocation stops further activity immediately.
Practitioner guidance
- Define dedicated identities for each agent Avoid shared credentials or user impersonation.
- Enforce short-lived tokens and narrow scopes Set token lifetimes to the minimum practical window and restrict scopes to the exact API actions the agent needs.
- Partition permissions by tenant and workload Use separate credentials, scopes, and audit trails per customer or organisational boundary.
Bottom line: AI agent authentication only becomes safe when organisations treat OAuth and OIDC as controls for non-human runtime behaviour, not just login plumbing.

Agent authentication is now an NHI governance problem, not a user-login variant: OAuth and OIDC become structurally different when the subject is a machine actor that can act continuously and independently. The real design issue is not whether the protocol works, but whether identity ownership, scope design, and revocation are built for non-human runtime behaviour. Practitioners should treat agent authentication as lifecycle governance for a machine identity estate.
A few things that frame the scale:
- 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between short-lived tokens and least privilege for AI agents?
A: Short-lived tokens reduce how long a leaked credential remains usable, while least privilege limits what that credential can do while it is valid. Teams need both because expiry alone does not stop overreach, and narrow scope alone does not limit exposure if a token is stolen early.
