Deleting unnecessary root access keys

Once you have credentials from the Credential Factory or are logged into an EC2 instance from the Instance Factory, verify that you can run substrate assume-role -management. If so, you can finally delete your root and OrganizationAdministrator access keys. They’re simply security liabilities. Let’s delete them:

1. Run substrate delete-static-access-keys to delete access keys for the OrganizationAdministrator IAM user in your management account
2. Visit https://console.aws.amazon.com/iam/home#/security_credentials while signed in using the root email address, password, and second factor on your management account
3. Open the Access keys (access key ID and secret access key) section
4. Click Delete next to your root access key

From now on, the Credential and Instance Factories are how you access your organization via the command line.
