What is AWS SSO?

AWS Single Sign-On (SSO), now known as AWS IAM Identity Center, is a cloud-based service that enables you to centrally manage access to multiple AWS accounts and applications. It allows users to sign in once and then access all their assigned AWS resources without needing to re-enter credentials. AWS SSO integrates with existing identity providers like Active Directory or Okta, or you can use the AWS SSO directory. It simplifies access management and improves security posture by providing a single point of control for user permissions.
