 # GCP Authentication in Prowler
 
-## Default Authentication
+## Required Permissions
 
-By default, Prowler uses your User Account credentials. You can configure authentication as follows:
+Prowler for Google Cloud requires the following permissions:
 
-- `gcloud init` to use a new account, or
-- `gcloud config set account <account>` to use an existing account.
+### IAM Roles
+- **Reader (`roles/reader`)** – Must be granted at the **project, folder, or organization** level to allow scanning of target projects.
 
-Then, obtain your access credentials using: `gcloud auth application-default login`.
+### Project-Level Settings
 
-## Using Service Account Keys
+At least one project must have the following configurations:
 
-Alternatively, Service Account keys can be generated and downloaded in JSON format. Follow the steps in the Google Cloud IAM guide (https://cloud.google.com/iam/docs/creating-managing-service-account-keys) to create and manage service account keys. Provide the path to the key file using:
+- **Identity and Access Management (IAM) API (`iam.googleapis.com`)** – Must be enabled via:
 
-```console
-prowler gcp --credentials-file path
-```
+    - The [Google Cloud API UI](https://console.cloud.google.com/apis/api/iam.googleapis.com/metrics), or
+    - The `gcloud` CLI:
+    ```sh
+    gcloud services enable iam.googleapis.com --project <your-project-id>
+    ```
+
+- **Service Usage Consumer (`roles/serviceusage.serviceUsageConsumer`)** IAM Role – Required for resource scanning.
+
+- **Quota Project Setting** – Define a quota project using either:
+
+    - The `gcloud` CLI:
+    ```sh
+    gcloud auth application-default set-quota-project <project-id>
+    ```
+    - Setting an environment variable:
+    ```sh
+    export GOOGLE_CLOUD_QUOTA_PROJECT=<project-id>
+    ```
 
 ???+ note
     `prowler` will scan the GCP project associated with the credentials.
 
-## Using an access token
-
-If you already have an access token (e.g., generated with `gcloud auth print-access-token`), you can run Prowler with:
-
-```bash
-export CLOUDSDK_AUTH_ACCESS_TOKEN=$(gcloud auth print-access-token)
-prowler gcp --project-ids <project-id>
-```
-
-???+ note
-    If using this method, it's recommended to also set the default project explicitly:
-    ```bash
-    export GOOGLE_CLOUD_PROJECT=<project-id>

 ## Credentials lookup order
 
 Prowler follows the same credential search process as [Google authentication libraries](https://cloud.google.com/docs/authentication/application-default-credentials#search_order), checking credentials in this order:

-## Required Permissions
-
-To ensure full functionality, Prowler for Google Cloud needs the following permissions to be set:
-
-- **Reader (`roles/reader`) IAM role**: granted at the project / folder / org level in order to scan the target projects
-
-- **Project level settings**: you need to have at least one project with the below settings:
-    - Identity and Access Management (IAM) API (`iam.googleapis.com`) enabled by either using the
-    [Google Cloud API UI](https://console.cloud.google.com/apis/api/iam.googleapis.com/metrics) or
-    by using the gcloud CLI `gcloud services enable iam.googleapis.com --project <your-project-id>` command
-    - Set the quota project to be this project by either running `gcloud auth application-default set-quota-project <project-id>` or by setting an environment variable:
-    `export GOOGLE_CLOUD_QUOTA_PROJECT=<project-id>`
 
 
-The above settings must be associated to a user or service account.
