Option 1: Adding Your Role ARN to a New Account

  3. Select Roles and then click Create Role.
  4. In the following screen, select "Another AWS account"
  5. Establish Trust - Enter the following values:
    • In Account ID, enter 432263259397
    • In External ID, enter the External ID from the New Account page in Cloudyn. (For example, “Companyname1234567890123”). Do not change the “Require MFA” box (It should remain unchecked.)
  6. Click Next: Permissions.
  7. Attach Policy - Select ReadOnlyAccess and then click Next: Review. (Tip: Use the search filter and type readonlyaccess. ReadOnlyAccess appears at the end of the search results list).
  8. Review - Enter a name for the new role, check to make sure you entered the correct information and then click Create Role. The list of your Roles appears.
  9. Select the role you just created and copy the Role ARN.
  10. Return to the Cloudyn New AWS Account page and paste the Role ARN in the relevant field.. 
  11. Click Save.The Role ARN is added to the account. 

Option 2: Adding Your IAM User ARN for a new account

*We strongly recommend this update on all linked accounts.

  1. On your AWS Management Console, click IAM (Secure AWS Access Control) or alternatively navigate to this link: .
  2. In the left Navigation pane, select Users.
  3. Click Create New Users.
  4. Fill in the name of the user. Make sure that the "Generate an access key" checkbox is selected.
  5. Click Create.
  6. In the notification window, click Download Credentials. Save the file in a secure location – it will contain the access and the secret key that you’ll need to complete your registration.
  7. After saving the file, close the window.

Important! Amazon does not keep user credentials – if the file is lost, you will have to delete the credentials and create a new set. 


STEP 2 - Activate detailed billing

This step is required for setting up your consolidated account. 

 1. Go to your Amazon IAM dashboard. Depending on the access type you chose when adding your AWS account click on Users or Roles.

2. Click on the Cloudyn read-only user/role you setup in Step 1. A summary of details appears.

3. Copy and save your ARN (Amazon Resource Name) from this section and keep it available for you to use in later steps.

4. Go to your S3 Console and click Create Bucket.  Enter the desired bucket name and region and then click Create.  

5. Select the desired bucket and then click on Permissions. Click on Add bucket policy.

9. Select all four billing reports as shown in the screenshot below and click Save Preferences
