Before access starts, decide who can revoke it and how; afterward, check both authorization and audit records. The details differ across AWS, Google Cloud, and Microsoft Azure, so there is no single cross-cloud command or token lifetime.
Plan the access before granting it
First identify the agent runtime, the target resource, the operations the task requires, and whether the agent will act as itself or under delegated user authority. That distinction matters: an agent operating under a user’s authority can inherit a different access path from one using a dedicated workload identity.
- Choose a dedicated identity. Use an identity for the agent or its specific function, rather than a shared administrator identity. Prefer a provider-supported role, workload identity, managed identity, or service-account impersonation over a long-lived access key in a prompt, tool configuration, or application.
- Define the minimum permissions. Specify the required actions and the narrowest practical resource scope. Keep read, write, delete, and administrative powers separate when the task does not require them together.
- Set an end point. Choose a short credential session or an explicit time-bound activation or access grant. A credential’s expiration and the authorization behind it are different controls: changing a policy may affect requests made with a still-valid token, while a separate resource grant may continue to authorize access.
- Set the human and policy checks. Decide who authorizes the access and which high-impact tool calls require approval or another policy check before execution.
- Write the revocation plan. Identify the exact identity and grants to review, the operator allowed to revoke them, the action they will take, and the possible effect on other sessions before the agent starts.
These are implementation principles, not a single tested procedure that works identically across providers. Match the steps to the provider, credential type, runtime, and resource authorization model.
How the provider patterns differ
Use provider-specific documentation and settings for the selected credential mechanism. The figures below describe particular documented features, not a universal standard for AI agents or cloud tokens.

| Provider | Workload identity pattern | Documented time limit | Early-revocation consideration | Scope and audit |
|---|---|---|---|---|
| AWS | Assume an IAM role using AWS Security Token Service (STS) temporary credentials. | For the temporary-credential context described in AWS documentation accessed in 2026: a 900-second (15-minute) minimum, a 129,600-second (36-hour) maximum, and a 43,200-second (12-hour) default. Limits depend on the API and role configuration; check the selected operation. | AWS documents denying role sessions issued before a cutoff, or targeting a specific session with policy conditions. The role-wide cutoff can affect all earlier sessions of that role, and policy changes may take a few minutes to take effect. | Restrict actions and resources in the role policy. Review resource-based policies too; AWS notes an explicit deny may be needed. AWS documents CloudTrail logging for its temporary-delegation revocation procedure. |
| Google Cloud | Allow an authenticated principal to impersonate a service account with the required roles, generating short-lived credentials instead of distributing a service-account key. | Not stated as one general duration: check the selected API and credential type. | The cited guidance describes impersonation, but does not establish one general early-revocation operation for every credential and service combination. Confirm the applicable IAM and service behavior for the chosen setup. | Grant the service account only the roles the task needs. Google documents audit records for service-account impersonation; audit coverage can depend on the service. |
| Microsoft Azure and Entra | For supported Azure-hosted workloads, use a managed identity; Microsoft also describes workload identity for agent tool execution. For eligible Microsoft Entra roles, use Privileged Identity Management (PIM) activation; access packages can provide an agent identity with a start and end. | The cited Entra PIM role-assignment API overview gives an eight-hour maximum for eligible Microsoft Entra role activation, configurable lower in role settings. This is not a general Azure token lifetime. | Use the applicable role deactivation or time-bound access mechanism and check for other role assignments or resource grants. The cited sources do not establish one universal revocation operation for every Azure identity and grant. | Azure role assignments support scopes from resource through management group; use the smallest scope that fits. Microsoft’s agent guidance recommends least privilege per tool and auditing actions. |
Provider-specific details to check
AWS: role sessions and revocation blast radius
AWS STS temporary credentials are dynamically issued and stop working after expiration. For early revocation, AWS documents a role-session deny based on aws:TokenIssueTime to block sessions issued before a chosen time, as well as policy conditions that target a particular session. The cutoff procedure can affect every session of that role issued before the cutoff, so a role shared with other users or workloads has a wider blast radius. Check who else uses the role before applying a broad deny.
Do not assume every grant is controlled by the role’s identity policy. AWS warns that resource-based allows may need an explicit deny as well. Also distinguish the documented revocation procedure for temporary delegation sessions—which has a specific revoke operation and CloudTrail logging—from ordinary STS role-session revocation; they are not interchangeable.

Google Cloud: impersonation without distributing a key
Google Cloud’s temporary elevated-access pattern uses a service account carrying the desired roles and lets an authenticated principal impersonate it when needed. This avoids distributing a service-account key. Check the selected API’s credential lifetime, the IAM permissions required for impersonation, and the target service’s audit coverage; these details can vary with credential type and service.
Azure and Entra: separate workload identity from role activation
Managed identities can provide tokens to supported Azure-hosted services without developers managing secrets. Azure role assignments can apply to managed and workload identities at resource, resource-group, subscription, or management-group scope. Choose the narrowest scope that supports the task.

For eligible Microsoft Entra roles, PIM provides time-bound activation. The eight-hour maximum in the cited API overview applies to that role-activation mechanism, not to every Azure credential. Microsoft also describes access packages for AI agent identities: access can have a start and end and expire automatically unless extended.
Revoke access and verify the result
Expiration is useful, but do not treat deleting a local token cache as proof that access has been revoked. A client may hold another credential, and an alternate role assignment or resource-level grant may still authorize the operation. Use the revocation method that matches the credential and entitlement actually granted.

- Stop new work. Pause the agent or prevent it from making further tool calls while access is being changed.
- Apply the planned revocation. Revoke or deactivate the relevant session, role activation, or time-bound grant using the provider’s documented mechanism. For a broad role cutoff, first account for other sessions that may be affected.
- Review all authorization paths. Check the workload identity’s role or policy, resource-based permissions, other role assignments, and any separate grants that could still permit the action.
- Test authorization. From the relevant identity or execution path, make a representative request to the protected resource. Confirm that an action that should no longer be allowed is denied; a local credential-cache deletion alone is not a verification test.
- Inspect audit records. Confirm the identity that acted, the authorizing principal, the resource and action, timing, and any approval. Provider logs and service coverage vary, so check the records for the actual services involved.
If access remains, do not assume revocation failed or succeeded based on token age alone. Recheck alternate grants, policy evaluation, and the provider’s propagation behavior; AWS notes that policy changes in its role-session revocation procedure can take a few minutes to take effect.

- The agent workload identity and the human or system that authorized access.
- The actions and resources granted, plus the credential session or entitlement start and end.
- Approvals or policy checks for high-impact operations.
- The agent’s tool actions and the identity under which each action ran.
- The revocation action, verification request, and relevant audit events.
Microsoft’s agent guidance puts the permission rule succinctly: “Each tool should have the smallest useful permission set.” Treat tool boundaries as part of the access design, not as a reason to give every tool the full permissions of the workload.
