List and get service account keys

This page explains how to list and get service account keys using the Google Cloud console, the Google Cloud CLI, the Identity and Access Management API, or one of the Google Cloud Client Libraries.

Note: If you need to access resources from a workload that runs outside of Google Cloud, such as on Amazon Web Services (AWS) or Microsoft Azure, consider using Workload Identity Federation instead of service account keys. Federation lets your workloads access resources directly, using a short-lived access token, and eliminates the maintenance and security burden associated with service account keys.

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:

  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 service account credentials.

Required roles

To get the permissions that you need to list and get service account keys, ask your administrator to grant you the View Service Accounts (roles/iam.serviceAccountViewer) IAM role on either the project or the service account whose keys you want to manage. 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.

For more information, see Service Accounts roles.

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

List service account keys

You can list the service account keys for a service account using the Google Cloud console, the gcloud CLI, the serviceAccount.keys.list() method, or one of the client libraries.

The serviceAccount.keys.list() method is commonly used to audit service accounts and keys, or to build custom tooling for managing service accounts.

To find out which project your key belongs to, you can download the key as a JSON file and look at that file.

You might see keys listed that you did not create. These are keys created by Google and used by the Service Account Credentials API. To learn more, see Google-managed key pairs.

Console

1. In the Google Cloud console, go to the Service accounts page.

   Go to Service accounts

   The remaining steps appear in the Google Cloud console.

2. Select a project.
3. On the Service accounts page, click the email address of the service account whose keys you want to list.
4. Click Keys. The Google Cloud console displays a list of keys for the service account.

gcloud

Execute the gcloud iam service-accounts keys list command to list service account keys.

Replace the following values:

• SA_NAME: The name of the service account to list keys for.
• PROJECT_ID: Your Google Cloud project ID.

gcloud iam service-accounts keys list \
    --iam-account=SA_NAME@PROJECT_ID.iam.gserviceaccount.com

Output:

Get a service account key

You can use the gcloud CLI or the REST API to get the public key data for a service account key. In addition, you can use the Google Cloud console, the gcloud CLI, or the REST API to get metadata for the key, such as the algorithm that the key uses and whether the key is managed by you or by Google.

Note: You cannot get the private key data for a service account key. This data is available only when the key is created.

Console

To get the public key data for a service account key:

Use the gcloud CLI or the REST API. This data is not available in the Google Cloud console.

To get metadata for a service account key:

1. In the Google Cloud console, go to the Service accounts page.

   Go to Service accounts

   The remaining steps appear in the Google Cloud console.

2. Select a project.
3. On the Service accounts page, click the email address of the service account whose keys you want to list.
4. Click Keys. The Google Cloud console displays a list of keys for the service account, including metadata for each key.

gcloud

To get the public key data for a service account key:

Run the gcloud beta iam service-accounts keys get-public-key command:

gcloud beta iam service-accounts keys get-public-key KEY_ID \
    --iam-account=SA_NAME@PROJECT_ID.iam.gserviceaccount.com \
    --output-file=FILENAME

Provide the following values:

• KEY_ID: The ID of the public key you want to get. To find the key's ID, list all keys for the service account, identify the key that you want to get, and then copy its ID.
• SA_NAME: The name of the service account whose public key you want to get.
• PROJECT_ID: Your Google Cloud project ID.
• FILENAME: The file in which to save the public key data.

By default, the public key data is saved in X.509 PEM format. To get the raw public key, run the command with the additional flag --type=raw.

For example, the following command gets the public key data for the key c97cc34494c07c9b483701f28368f20145b9ef97, which belongs to the service account [e-mail], then saves the public key data to the file public_key.pem:

gcloud beta iam service-accounts keys get-public-key \
    c97cc34494c07c9b483701f28368f20145b9ef97 \
    --iam-account=[e-mail] \
    --output-file=public_key.pem

To get metadata for a service account key:

Run the gcloud iam service-accounts keys list command:

gcloud iam service-accounts keys list --iam-account=SA_NAME \
    --filter="name~KEY_ID" --format=json

Provide the following values:

• SA_NAME: The name of the service account for which you want key metadata.
• KEY_ID: The ID of the key for which you want metadata.

For example, the following command gets metadata for the key c97cc34494c07c9b483701f28368f20145b9ef97, which belongs to the service account [e-mail]:

gcloud iam service-accounts keys list \
    --iam-account=[e-mail] \
    --filter="name~c97cc34494c07c9b483701f28368f20145b9ef97" --format=json

REST

The projects.serviceAccounts.keys.get method returns information about a public key for a service account.

Before using any of the request data, make the following replacements:

• PROJECT_ID: Your Google Cloud project ID. Project IDs are alphanumeric strings, like my-project.
• SA_NAME: The name of the service account whose public key you want to get.
• KEY_ID: The ID of the public key you want to get. To find the key's ID, list all keys for the service account, identify the key that you want to get, and then copy its ID from the end of the name field. The key's ID is everything after keys/.
• KEY_TYPE: The format in which to return the public key. Use TYPE_X509_PEM_FILE for X.509 PEM format or TYPE_RAW_PUBLIC_KEY for the raw public key. If you omit this query parameter, the method returns metadata for the key, but it does not return the public key data.
