At the Account Type step of the wizard, select the type of IAM role that you want to add. The selected type defines what IAM role settings will be available at the next step of the wizard. You can select one of the following IAM role types:
- IAM Role — select this option if you want to add an IAM role that has permissions on resources of the initial AWS account.
- IAM Role from another account — select this option if you want to add a cross-account IAM role that has permissions on resources of another AWS account.
A cross-account IAM role in AWS is used to provide IAM users in the initial AWS account (trusted account) access to resources in another AWS account (trusting account). For details, see AWS Documentation.
