Frequently asked questions

When should I attach AWSSSOMemberAccountAdministrator?

The IAM Identity Center User Guide says it is intended for principals who perform the job role of an IAM Identity Center administrator. You can attach it to users, groups and roles. It grants administrative IAM Identity Center permissions across the AWS Organizations management account and member accounts, so attach it only where that scope is intended.

What does AWSSSOMemberAccountAdministrator grant?

It allows sso:*, sso-directory:*, identitystore:* and identitystore-auth:* on all resources, plus directory (ds:), AWS Organizations, IAM policy-listing and Access Analyzer validation actions that support administration. It allows registering and deregistering a delegated administrator (limited to the sso.amazonaws.com service principal) and the AWS KMS actions that IAM Identity Center instances with customer managed keys need.

What are the security risks of AWSSSOMemberAccountAdministrator?

The IAM Identity Center User Guide says a principal with the policy can fully manage all IAM Identity Center operations, including creating permission sets and assignments across member accounts, and that new administrative permissions are granted automatically as features are released. AWS managed policies don't grant least privilege permissions, and AWS updates to the policy affect every identity it is attached to.
