Account access manager lets you assign AWS account access to users and groups in your IAM Identity Center organization instance. You assign access using the IAM roles in your AWS accounts.
This document explains how to onboard the AWS Account Access application to Britive.
Once you have configured the Britive Identity Provider and an IAM role for the management AWS account, you can add the AWS Account Access application in Britive and proceed with the onboarding steps.
After onboarding, you can scan the application from Britive to get the details (such as permissions and accounts) associated with them. You can also check out and check in profiles from the onboarded AWS Account Access application.
