TL;DR: Access sprawl grows when API keys, OAuth grants, and personal access tokens are treated like static credentials, leaving invisible, long-lived access paths outside directory-led review, according to Token Security. The core failure is governance built for users, not bearer tokens that persist independently of identity lifecycle, so revocation, attribution, and least privilege all degrade.
Editorial analysis by NHI Mgmt Group, based on content published by Token Security: “How Access Sprawl Emerges When Tokens Are Treated as Credentials”.
Key questions
Q: What breaks when API keys and OAuth tokens are treated like ordinary user credentials?
A: Governance breaks because the access object outlives the user review cycle.
Q: Why do token sprawl and standing privilege increase lateral movement risk?
A: Because a token with broad scope can be copied across environments and reused without the interactive checks that protect human logins.
Q: How should security teams detect token sprawl before it becomes a breach issue?
A: Look for tokens that are invisible to IAM review, repeatedly reused across services, or still active after the related application or project has ended.
Practitioner guidance
- Inventory token-based access paths Scan repositories, CI/CD pipelines, SaaS consoles, and local configuration stores for active API keys, OAuth grants, and personal access tokens, then tie each token to an owner and business purpose.
- Classify tokens as governable access subjects Assign lifecycle ownership, scope, and revocation responsibility to each token instead of treating it as an inert secret stored for safekeeping.
- Reduce standing privilege at issuance Issue the narrowest workable scopes, reject full-access defaults, and make environment-bound use the baseline for non-human credentials.
Bottom line: Token sprawl is the visibility gap left when bearer access is handled as a secret instead of a governed access object.

Access sprawl is an authorization problem, not just an identity problem. IAM programmes that focus on users, groups, and login events miss the much larger layer of bearer access created by tokens, API keys, and OAuth grants. Those objects can persist independently of the human account that minted them, which means governance built around directories will always undercount the real access surface. Practitioners need to treat authorization paths as first-class inventory, not as a side effect of identity administration.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
- Nearly 60% of IT leaders cite restrictive cost and complexity as a weakness of legacy identity governance, according to the 2025 State of Identity Governance Report.
A question worth separating out:
Q: Should organisations govern bearer tokens differently from human user accounts?
A: Yes. Human accounts, service roles, and bearer tokens do not share the same lifecycle or review model, so they should not be governed through the same control workflow. Tokens need ownership, purpose binding, expiry, and revocation handling that reflects how they are actually used in automation and integrations.
