By federating Okta to Amazon Web Services (AWS) Identity and Access Management (IAM) accounts, end users get single sign-on access to all their assigned AWS roles with their Okta credentials. In each AWS account, administrators set up federation and configure AWS roles to trust Okta. When users sign-in to AWS, they get Okta single sign-in experience to see their assigned AWS roles. They can then select a desired role, which defined their permissions for the duration of their authenticated session. Customers with large numbers of AWS Accounts, check out the AWS Single Sign-On app as an alternative.
