Disable and enable service accounts

This page explains how to disable and enable service accounts using the Identity and Access Management (IAM) API, the Google Cloud console, and the gcloud CLI.

Before you begin

• Enable the IAM API.

  Enable the API

• Set up authentication.

  Select the tab for how you plan to use the samples on this page:

  Console

  When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

  gcloud

  In the Google Cloud console, activate Cloud Shell.

  Activate Cloud Shell

  At the bottom of the Google Cloud console, a Cloud Shell session starts and displays a command-line prompt. Cloud Shell is a shell environment with the Google Cloud CLI already installed and with values already set for your current project. It can take a few seconds for the session to initialize.

  C#

  To use the .NET samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  For more information, see Set up authentication for a local development environment in the Google Cloud authentication documentation.

  C++

  To use the C++ samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  For more information, see Set up authentication for a local development environment in the Google Cloud authentication documentation.

  Go

  To use the Go samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  For more information, see Set up authentication for a local development environment in the Google Cloud authentication documentation.

  Java

  To use the Java samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  For more information, see Set up authentication for a local development environment in the Google Cloud authentication documentation.

  Python

  To use the Python samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. To initialize the gcloud CLI, run the following command:

     gcloud init

  3. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

  For more information, see Set up authentication for a local development environment in the Google Cloud authentication documentation.

  REST

  To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

  Install the Google Cloud CLI, then initialize it by running the following command:

  gcloud init

  For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

• Understand IAM service accounts

Required roles

To get the permissions that you need to manage service accounts, ask your administrator to grant you the Service Account Admin (roles/iam.serviceAccountAdmin) IAM role on the project. For more information about granting roles, see Manage access to projects, folders, and organizations.

You might also be able to get the required permissions through custom roles or other predefined roles.

To learn more about this role, see Service Accounts roles.

IAM basic roles also contain permissions to manage service accounts. You should not grant basic roles in a production environment, but you can grant them in a development or test environment.

Disable a service account

Similar to deleting a service account, when you disable a service account, applications will no longer have access to Google Cloud resources through that service account. If you disable the default App Engine and Compute Engine service accounts, the instances will no longer have access to resources in the project. If you attempt to disable an already disabled service account, it will have no effect.

Unlike deleting a service account, disabled service accounts can easily be re-enabled as necessary. We recommend disabling a service account before deleting it to make sure no critical applications are using the service account.

Enable a service account

After enabling a disabled service account, applications will regain access to Google Cloud resources through that service account.

You can enable a disabled service account whenever you need to. If you attempt to enable an already enabled service account, it will have no effect.
