AWS IAM Identity Center
AWS IAM Identity Center handles single sign-on access for AWS accounts and apps. It centralizes identity management, letting you control who gets into which resources across your organization. This setup simplifies access governance by replacing scattered credentials with a unified entry point for your team’s daily work.
It fits teams needing centralized SSO without a free tier option. Since there is no free tier, you pay as you go for usage. This pricing model means costs scale with activity, so you should monitor usage to avoid unexpected charges.
