Creating OrganizationAccountAccessRole for an invited account with Amazon Organizations

By default, if you create a member account as part of your organization, Amazon automatically creates a role in the account that grants administrator permissions to IAM users in the management account who can assume the role. By default, that role is named OrganizationAccountAccessRole. For more information, see Accessing a member account that has OrganizationAccountAccessRole with Amazon Organizations.

However, member accounts that you invite to join your organization do not automatically get an administrator role created. You have to do this manually, as shown in the following procedure. This essentially duplicates the role automatically set up for created accounts. We recommend that you use the same name, OrganizationAccountAccessRole, for your manually created roles for consistency and ease of remembering.

Amazon Web Services Management Console
To create an Amazon Organizations administrator role in a member account

  1. Sign in to the IAM console at https://console.amazonaws.cn/iam/. You must sign in as an IAM user or assume an IAM role in the member account that has permissions to create IAM roles and policies. You can use the administrator user that was created for you when you created the member account.

  2. In the IAM console, navigate to Roles and then choose Create role.

  3. Choose Amazon Web Services account, and then select Another Amazon Web Services account.

  4. Enter the 12-digit account ID number of the management account that you want to grant administrator access to. Under Options, please note the following:

    • For this role, because the accounts are internal to your company, you should not choose Require external ID. For more information about the external ID option, see When should I use an external ID? in the IAM User Guide.

    • If you have MFA enabled and configured, you can optionally choose to require authentication using an MFA device. For more information about MFA, see Using multi-factor authentication (MFA) in Amazon in the IAM User Guide.

  5. Choose Next.

  6. On the Add permissions page, choose the Amazon managed policy named AdministratorAccess and then choose Next.

  7. On the Name, review, and create page, specify a role name and an optional description. We recommend that you use OrganizationAccountAccessRole, for consistency with the default name assigned to the role in new accounts. To commit your changes, choose Create role.

  8. Your new role appears on the list of available roles. Choose the new role's name to view its details, paying special note to the link URL that is provided. Give this URL to users in the member account who need to access the role. Also, note the Role ARN because you need it in step 15.

  9. Sign in to the IAM console at https://console.amazonaws.cn/iam/. This time, sign in as a user in the management account who has permissions to create policies and assign the policies to users or groups.

  10. Navigate to Policies and then choose Create policy.

  11. For Service, choose STS.

  12. For Actions, start typing AssumeRole in the Filter box and then select the check box next to it when it appears.

  13. Under Resources, ensure that Specific is selected and then choose Add ARNs.

  14. Enter the Amazon member account ID number and then enter the name of the role that you previously created in steps 1–8. Choose Add ARNs.

  15. If you're granting permission to assume the role in multiple member accounts, repeats steps 14 and 15 for each account.

  16. Choose Next.

  17. On the Review and create page, enter a name for the new policy and then choose Create policy to save your changes.

  18. Choose User groups in the navigation pane and then choose the name of the group (not the check box) that you want to use to delegate administration of the member account.

  19. Choose the Permissions tab.

  20. Choose Add permissions, choose Attach policies, and then select the policy that you created in steps 11–18.

The users who are members of the selected group now can use the URLs that you captured in step 9 to access each member account's role. They can access these member accounts the same way as they would if accessing an account that you create in the organization.
