The first role you need to create is the **management account role**. This role allows Prowler to discover your Organization structure — listing accounts, OUs, and hierarchy.
<Warning>
**This role must be created manually.** Organizational CloudFormation StackSets do not deploy to the management account itself — this is an AWS limitation, not a Prowler one. StackSets with service-managed permissions only target member accounts. Similarly, the Prowler Quick Create link only deploys the role to member accounts.
**StackSets do not deploy to the management account.** Organizational CloudFormation StackSets with service-managed permissions only target member accounts — this is an AWS limitation, not a Prowler one. You must create the management account role separately, either via the Quick Create link ([Option A](#option-a-quick-create-link-fastest)) or manually ([Option B](#option-b-create-the-role-manually)).
</Warning>
<Note>
**The role must be named `ProwlerScan`** — the same name as the role deployed to member accounts via StackSet. Prowler expects a consistent role name across all accounts in the Organization. If you use a different name, connection tests and scans will fail for the management account.
</Note>
### Create the IAM Role
### Option A: Quick Create Link (Fastest)
The Prowler wizard provides a one-click link that opens the AWS Console with the CloudFormation template pre-configured. This creates a **CloudFormation Stack** (not a StackSet) that deploys the ProwlerScan role with Organizations permissions enabled in your management account.
<Tip>
**[Open Quick Create Stack in AWS Console →](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/quickcreate?templateURL=https%3A%2F%2Fprowler-cloud-public.s3.eu-west-1.amazonaws.com%2Fpermissions%2Ftemplates%2Faws%2Fcloudformation%2Fprowler-scan-role.yml&stackName=Prowler&param_EnableOrganizations=true)**
Opens the CloudFormation Console with the Prowler scan role template and `EnableOrganizations=true` pre-filled. You will need to enter the **ExternalId** parameter manually — copy it from the Prowler wizard ([Step 4](#step-4-authenticate-with-your-management-account)).
</Tip>
1. Click **[Open Quick Create Stack in AWS Console →](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/quickcreate?templateURL=https%3A%2F%2Fprowler-cloud-public.s3.eu-west-1.amazonaws.com%2Fpermissions%2Ftemplates%2Faws%2Fcloudformation%2Fprowler-scan-role.yml&stackName=Prowler&param_EnableOrganizations=true)** or use the **Create Stack in Management Account** button in the Prowler wizard (which also pre-fills the ExternalId).
2. Enter the **ExternalId** parameter if not pre-filled.
3. Check **"I acknowledge that AWS CloudFormation might create IAM resources with custom names"** and click **Create stack**.
4. Wait for the stack to reach **CREATE_COMPLETE** status.
Take note of the **Role ARN** from the stack's **Outputs** tab — you will need it in the wizard.
### Option B: Create the Role Manually

### Option A: Using the Prowler Quick Create Link (Recommended)
The Prowler wizard provides a one-click link that opens the AWS Console with everything pre-configured.
<Warning>
**The Quick Create link creates a Stack, not a StackSet.** The link in the Prowler wizard creates a CloudFormation **Stack** that deploys the ProwlerScan role in your management account only ([Step 1](#step-1-create-the-management-account-role)). To deploy the role across **member accounts**, you must create a StackSet manually as described below. AWS does not support Quick Create links for StackSets.

**[Open Quick Create in AWS Console →](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/quickcreate?templateURL=https%3A%2F%2Fprowler-cloud-public.s3.eu-west-1.amazonaws.com%2Fpermissions%2Ftemplates%2Faws%2Fcloudformation%2Fprowler-scan-role.yml&stackName=Prowler)**
**[Open StackSets Console →](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacksets/create)**
Opens the CloudFormation Console with the Prowler scan role template and parameters pre-configured. You can also find this link in the Prowler wizard during [Step 4: Authentication](#step-4-authenticate-with-your-management-account).
Opens the CloudFormation StackSets creation page directly. You will need to paste the template URL and ExternalId manually.
</Tip>
1. Review the pre-filled parameters:
- **Template URL**: Points to the official [Prowler scan role template](https://prowler-cloud-public.s3.eu-west-1.amazonaws.com/permissions/templates/aws/cloudformation/prowler-scan-role.yml) hosted on Prowler's public S3 bucket.
- **ExternalId**: Pre-filled with your tenant's External ID when clicking the link from the Prowler Cloud wizard. If you open this link directly, you will need to enter the External ID manually.
{/* TODO: screenshot of AWS Console Quick Create page showing pre-filled parameters */}
2. Under **Deployment targets**, select:
- **Deploy to organization** to deploy to all accounts, or
- **Deploy to organizational units (OUs)** and specify the OU IDs you want to cover.
3. Review the settings and click **Create StackSet**. AWS will begin deploying the ProwlerScan role to every target account.
### Option B: Manual StackSet Deployment
If you prefer full control over the deployment:
1. Open the [AWS CloudFormation Console](https://console.aws.amazon.com/cloudformation/) in your management account.
2. Go to **StackSets > Create StackSet**.
3. Choose **Service-managed permissions**.
4. Use this template URL:
1. Click the link above or navigate to **CloudFormation > StackSets > Create StackSet** in your management account.
2. Choose **Service-managed permissions**.
3. Select **Amazon S3 URL** as the template source and paste the following URL:
```
https://prowler-cloud-public.s3.eu-west-1.amazonaws.com/permissions/templates/aws/cloudformation/prowler-scan-role.yml
```
5. Set the **ExternalId** parameter to the External ID shown in the Prowler wizard.
6. Choose your deployment targets (entire organization or specific OUs).
7. Select the AWS regions where you want the role deployed.

## Step 4: Authenticate with Your Management Account
### Copy the External ID
The wizard's **Authentication Details** page guides you through three actions: deploying the roles in AWS, entering the management account Role ARN, and confirming the deployment.
The wizard displays a **Prowler External ID** — auto-generated and unique to your tenant. Click the copy icon to copy it. If you haven't already configured the trust policy on your management account role ([Step 1](#step-1-create-the-management-account-role)), do so now using this External ID.
### External ID
The wizard displays a **Prowler External ID** at the top — auto-generated and unique to your tenant. Click the copy icon to copy it. You will need this External ID for both the management account Stack and the member accounts StackSet.
### Deploy the Roles
The wizard provides two deployment actions:
1. **Create Stack in Management Account** — opens a Quick Create link that deploys the ProwlerScan role with `EnableOrganizations=true` in your management account ([Step 1](#step-1-create-the-management-account-role)). The External ID is pre-filled.
2. **Open StackSets Console** — links to the CloudFormation StackSets console where you create a StackSet for member accounts ([Step 2](#step-2-deploy-the-cloudformation-stackset)). Copy the template URL shown in the wizard and paste the External ID manually.

Paste the **Role ARN** of the management account role you created in [Step 1](#step-1-create-the-management-account-role) into the **Management Account Role ARN** field.
The ARN follows this format:
