Multiple Account API Access Setup

Using CloudFormation StackSets, it is possible to deploy API access for all sub-accounts that the payer account sees in the same organization. This guide shows how to use this ability to onboard your accounts.

As each linked accounts are automatically created with Alphaus IAM role, these accounts are also automatically onboarded to Octo.
