AWS IAM Identity Center

AWS service (formerly AWS Single Sign-On) that centrally manages workforce access to multiple AWS accounts and applications.

Definition

IAM Identity Center connects to an identity source such as its own directory, Active Directory or an external IdP like Microsoft Entra ID or Okta via SAML and SCIM. Administrators assign users and groups to accounts with permission sets, which are provisioned as roles, giving users single sign-on with temporary credentials.

Example

Employees sign in through Entra ID and choose a ReadOnly or Admin permission set for each AWS account in the organization.

Exam tip

Identity Center is the recommended way to give humans access to multiple accounts; it was renamed from AWS SSO.
