+    1. Download the [Prowler Scan Role Template](https://raw.githubusercontent.com/prowler-cloud/prowler/refs/heads/master/permissions/templates/cloudformation/prowler-scan-role.yml)

-```console
-export AWS_ACCESS_KEY_ID="ASXXXXXXX"
-export AWS_SECRET_ACCESS_KEY="XXXXXXXXX"
-export AWS_SESSION_TOKEN="XXXXXXXXX"

-These credentials must be associated with a user or role with the necessary permissions to perform security checks.
+        ![Download Role Template](./img/download-role-template.png)

+    2. Open the [AWS Console](https://console.aws.amazon.com), search for **CloudFormation**

+        ![CloudFormation Search](./img/cloudformation-nav.png)

-## AWS Profiles
+    3. Go to **Stacks** and click "Create stack" > "With new resources (standard)"

-Specify a custom AWS profile using the following command:
+        ![Create Stack](./img/create-stack.png)

-```console
-prowler aws -p/--profile <profile_name>

-For IAM entities requiring Multi-Factor Authentication (MFA), use the `--mfa` flag. Prowler prompts for the following values to initiate a new session:
+    5. Click "Next", provide a stack name and the **External ID** shown in the Prowler Cloud setup screen

- **ARN of your MFA device**
- **TOTP (Time-Based One-Time Password)**

+
+        !!! info
+            An **External ID** is required when assuming the *ProwlerScan* role to comply with AWS [confused deputy prevention](https://docs.aws.amazon.com/IAM/latest/UserGuide/confused-deputy.html).

+
+    To provision the scan role using Terraform:
+
+    1. Run the following commands:
+
+        ```bash
+        terraform init
+        terraform plan
+        terraform apply
+        ```
+
+    2. During `plan` and `apply`, provide the **External ID** when prompted, which is available in the Prowler Cloud or Prowler App UI:
+
+        ![Get External ID](./img/get-external-id-prowler-cloud.png)
+
+    > 💡 Note: Terraform will use the AWS credentials of the default profile.

+## Credentials
+=== "Long term credentials"
+
+    1. Go to the [AWS Console](https://console.aws.amazon.com), open **CloudShell**
+
+        ![AWS CloudShell](./img/aws-cloudshell.png)
+
+    2. Run:
+
+        ```bash
+        aws iam create-access-key
+        ```
+
+    3. Copy the output containing:
+
+        - `AccessKeyId`
+        - `SecretAccessKey`
+
+        ![CloudShell Output](./img/cloudshell-output.png)
+
+=== "Short term credentials (Recommended)"
+
+    Use the [AWS Access Portal](https://docs.aws.amazon.com/singlesignon/latest/userguide/howtogetcredentials.html) or the CLI:
+
+    1. Retrieve short-term credentials for the IAM identity using this command:
+
+        ```bash
+        aws sts get-session-token --duration-seconds 900
+        ```
+
+        ???+ note
+            Check the aws documentation [here](https://docs.aws.amazon.com/IAM/latest/UserGuide/sts_example_sts_GetSessionToken_section.html)

+    2. Copy the output containing:
+
+        - `AccessKeyId`
+        - `SecretAccessKey`
+        - `SessionToken`
