One of the best features AWS IAM Identity Center offers is the permission set, which is one of the best. Then there are the temporary credentials via SSO, the multi-account governance, and the centralized identity management. Those are good features that I believe assist developers, and another feature I can say is one of the best is the improved security with temporary credentials. The feature I find myself relying on the most day-to-day would be the centralized identity management and multi-account governance. It allows me to check what other developers are doing and since I am the admin, I can also revoke the access they have to the AWS accounts.
