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.
Why bearer tokens should not be governed like user accounts
Bearer tokens are not people, and they do not have the same lifecycle, assurance, or review needs as a human account. A token is a portable access artifact that can be copied, replayed, scoped, and revoked independently of any one person. That means governance has to focus on issuance, intended use, expiry, and revocation rather than employee status or joiner-mover-leaver workflows.
That difference matters because a token can outlive the person who requested it, be embedded in automation, or be shared across systems. Human account governance is usually organized around ownership, identity proofing, and periodic recertification of access. Token governance is closer to credential control, where the key questions are who controls it, what it can reach, how long it should live, and how quickly it can be invalidated if exposed.
Bearer token handling becomes especially important when the token is used in machine-to-machine or delegated access flows. The design goal is to keep the access artifact narrow and short-lived enough that a leak does not become broad, durable access. Standards such as RFC 6749: The OAuth 2.0 Authorization Framework and RFC 9700: Best Current Practice for OAuth 2.0 Security both reinforce that tokens need audience, scope, and theft resistance rather than human-style review alone.
What changes in governance when the subject is a token instead of a user
A human account is governed as an identity with an owner, authentication factors, role assignments, and a review cadence tied to employment or contractual status. A bearer token is governed as a secret-bearing credential with a purpose and a usage boundary. That means the control model should include token inventory, issuing system, intended audience, expiration, refresh behavior, and revocation path.
Ownership is still required, but it is not the same as account ownership. For a token, ownership means there is a named system or team responsible for the token’s purpose, rotation, and retirement. Purpose binding matters because a token issued for one integration should not silently become a general access artifact. When organizations blur these lines, they often miss dormant tokens, overbroad scopes, and stale integrations that remain active long after the original use case has changed.
Bearer-token governance also has to account for binding and replay resistance. Where feasible, organizations should prefer sender-constrained designs rather than treating every token as a reusable key. That is why RFC 9449: OAuth 2.0 Demonstrating Proof of Possession and RFC 8705: OAuth 2.0 Mutual-TLS Client Authentication and Certificate-Bound Access Tokens are relevant when you want stolen tokens to be less useful outside the intended client.
How to review, rotate, and revoke bearer tokens safely
Token review should be event-driven and inventory-driven, not employment-driven. The operational questions are whether the token is still needed, whether the scope matches the current integration, whether the expiry is appropriate, and whether a rotation plan exists if the issuing system, integration, or downstream service changes. For this reason, token lifecycle controls should include expiry, rotation, revocation testing, and confirmation that the consuming application can recover cleanly after renewal.
Revocation is where bearer-token governance often fails in practice. If a token is embedded in code, a build pipeline, or a third-party integration, simply deleting a user account may not stop access immediately. You need a revocation path that reaches the issuing service, plus a way to discover where the token was distributed. API Key Management Guide and Token and Session Security Guide both reinforce the practical controls around scoping, lifetime, rotation, and replay resistance that token programs need.
Long-lived tokens deserve extra scrutiny because they behave more like standing credentials than transient access. The safer pattern is to shorten lifetimes, automate renewal, and separate human approval from machine use where possible. If a token must be long-lived, the compensating controls should be stronger monitoring, tighter scope, and a clear emergency invalidation process.
Risk and Threat Considerations
Bearer tokens are attractive to attackers because possession is enough. If a token is stolen from code, logs, browsers, support systems, or a compromised integration, it can usually be replayed without needing the original user’s password or MFA prompt. The result is durable access that may survive account changes unless the token is explicitly revoked or expires quickly.
Failure mechanism: Organizations apply human-account governance to a bearer token, then miss scope drift, stale distribution, and delayed revocation. That leaves an attacker or unauthorized integration with a reusable credential that can continue to authenticate even after the originating user relationship has changed.
Impact: The exposed token can become a persistent entry point for data access, lateral movement, or API abuse, especially when it is broadly scoped or used across multiple systems.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 addresses the attack surface, NIST SP 800-53 Rev 5 sets the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Bearer tokens are authenticators that need lifecycle, renewal, and revocation control. |
| AC-6 — Least Privilege | Token governance should restrict access to the minimum required by the integration. | |
| Recommendation — Manage bearer tokens as authenticators with controlled issuance, rotation, and revocation. Constrain token privileges to the smallest necessary access path. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Token access needs separate control rules, ownership, and review from user accounts. |
| Recommendation — Define token-specific access control rules for issuance, review, and revocation. | ||
| OWASP Non-Human Identity Top 10 | NHI-02 — Secret Leakage | Bearer tokens are secrets whose exposure can enable unauthorized access. |
| NHI-07 — Long-Lived Secrets | Bearer tokens often become risky when they remain valid far longer than needed. | |
| Recommendation — Scan for leaked tokens and rotate any exposed token immediately. Shorten token lifetimes and replace standing tokens with expiring credentials. | ||
Practitioner Guidance
What to prioritise: Treat bearer tokens as a separate governance class from user accounts. The first control objective is an accurate inventory of where tokens exist, who owns them, what they can access, and when they expire.
Decision rule: If a bearer token can reach production data or automation, require expiry, narrow scope, and a defined revocation path before you accept it as a stable integration mechanism. If you cannot demonstrate those controls, the token is already over-privileged for its risk.
What to verify: Confirm that token review is tied to application ownership and change management, not to HR-driven account review. The review evidence should show issuance purpose, last rotation, current consumer, and successful revocation testing.
Common mistake: Assuming that disabling a person’s account fully removes access when the real exposure sits in a still-valid token issued to an app, pipeline, or partner integration.
Practitioner takeaway: Human identity governance tells you whether a person should still have access, but bearer-token governance tells you whether a reusable credential should exist at all, and for how long.
