TL;DR: Authentication and authorization are distinct control layers, and Ory argues that conflating them is a common root cause of broken access control. The practical issue is not terminology, but the handoff between verified identity and policy enforcement, which IAM and application teams still mis-implement.
NHIMG editorial — based on content published by Ory: Authorization vs Authentication: 5 Key Differences
Questions worth separating out
Q: How should security teams separate authentication from authorization in practice?
A: Treat authentication as the control that proves identity, and authorization as the control that limits actions after identity is established.
Q: Why does broken access control happen even when login works correctly?
A: Because login only proves identity.
Q: What do organisations get wrong about role-based access control?
A: They often let roles accumulate exceptions until the role catalogue no longer reflects actual work.
Practitioner guidance
- Separate authentication from authorization services Keep credential validation, session issuance, and policy evaluation in different control paths so a login success never implies a permission grant.
- Audit every protected endpoint for an explicit policy decision Inspect application routes, admin panels, and internal APIs to confirm each one calls an authorization check after identity verification.
- Define the claim set that authorization is allowed to trust Document which identity claims, attributes, roles, or relationships each policy engine may consume, then validate that upstream authentication systems issue those claims consistently.
What's in the full article
Ory's full post covers the operational detail this post intentionally leaves for the source:
- Implementation patterns for separating login flows from policy enforcement in production systems
- Concrete examples of RBAC, ABAC, and ReBAC decisions across real application architectures
- The engineering rationale for keeping authentication and authorization as independently testable services
- Protocol-specific handling for sessions, tokens, and claims in modern IAM stacks

Authentication and authorization only stay safe when the handoff between them is explicit. The article is right to treat the token or session as the boundary, not the endpoint. Many identity programmes document login well but under-specify the policy decision that follows, which is where real control failure begins. For practitioners, the governing question is whether every downstream action is evaluated against a separate access policy.
A few things that frame the scale:
- Only 44% of developers are reported to follow security best practices for secrets management, according to The State of Secrets in AppSec.
- The average estimated time to remediate a leaked secret is 27 days, which shows how quickly identity and credential mistakes can become durable exposure.
A question worth separating out:
Q: What is the difference between a valid session and valid authorisation?
A: A valid session means authentication succeeded and the system recognizes the requester as a verified identity. Valid authorisation means a separate policy engine has confirmed that the identity may perform the specific action on the specific resource. One proves who the requester is, the other proves what they are allowed to do.
