This page explains how to create and manage service accounts using the Identity and Access Management (IAM) API, the Google Cloud console, and the gcloud command- line tool By default, each project can have up to 100 service accounts that control access to your resources. You can request a quota increase if necessary. Learn more about quotas and limits ## Before you begin Enable the IAM API Understand IAM service accounts Install the Google Cloud CLI Required roles To get the permissions that you need to manage service accounts, ask your administrator to grant you the following IAM roles on the project: - To view service accounts and service account metadata: View Service Accounts ( roles/iam.serviceAccountViewer) - To view and create service accounts: Create Service Accounts ( roles/iam.serviceAccountCreator) - To view and delete service accounts: Delete Service Accounts ( roles/iam.serviceAccountDeleter) - To fully manage (view, create, update, disable, enable, delete, undelete, and manage access to) service accounts: Service Account Admin ( roles/iam.serviceAccountAdmin) For more information about granting roles, see Manage access To learn more about these roles, 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 ## Creating a service account When you create a service account, you must provide an alphanumeric ID ( in the samples below), such as `SA_NAME` my-service-account. The ID must be between 6 and 30 characters, and can contain lowercase alphanumeric characters and dashes. After you create a service account, you cannot change its name The service account's name appears in the email address that is provisioned during creation, in the format `SA_NAME`@ `PROJECT_ID`.iam.gserviceaccount.com Each service account also has a permanent, unique numeric ID, which is generated automatically You also provide the following information when you create a service account: is an optional description for the service account SA_DESCRIPTION is a friendly name for the service account SA_DISPLAY_NAME is the ID of your Google Cloud project PROJECT_ID After you create a service account, you might need to wait for 60 seconds or more before you use the service account. This behavior occurs because read operations are eventually consistent; it can take time for the new service account to become visible. If you try to read or use a service account immediately after you create it, and you receive an error, you can retry the request with exponential backoff Console In the Google Cloud console, go to the Create service accountpage Go to Create service account Select a Cloud project Enter a service account name to display in the Google Cloud console The Google Cloud console generates a service account ID based on this name. Edit the ID if necessary. You cannot change the ID later Optional: Enter a description of the service account If you do not want to set access controls now, click Doneto finish creating the service account To set access controls now, click Create and continueand continue to the next step Optional: Choose one or more IAM roles to grant to the service account on the project When you are done adding roles, click Continue Optional: In the Service account users rolefield, add members that can impersonate the service account Optional: In the Service account admins rolefield, add members that can manage the service account Click Doneto finish creating the service account gcloud CLI To create the service account, run the gcloud iam service-accounts createcommand: gcloud iam service-accounts create SA_NAME\ --description=" DESCRIPTION" \ --display-name=" DISPLAY_NAME" Replace the following values: : the name of the service account SA_NAME : an optional description of the service account DESCRIPTION : a service account name to display in the Google Cloud console DISPLAY_NAME - Optional: To grant your service account an IAM role on your project, run the gcloud projects add-iam-policy-bindingcommand: gcloud projects add-iam-policy-binding PROJECT_ID\ --member="serviceAccount: SA_NAME@ PROJECT_ID.iam.gserviceaccount.com" \ --role=" ROLE_NAME" Replace the following values: : the project ID PROJECT_ID : the name of the service account SA_NAME : a role name, such as ROLE_NAME roles/compute.osLogin - Optional: To allow users to impersonate the service account, run the gcloud iam service-accounts add-iam-policy-bindingcommand to grant a user the Service Account User role ( roles/iam.serviceAccountUser) on the service account: gcloud iam service-accounts add-iam-policy-binding SA_NAME@ PROJECT_ID.iam.gserviceaccount.com \ --member="user: USER_EMAIL" \ --role="roles/iam.serviceAccountUser" Replace the following values: : the project ID PROJECT_ID : the name of the service account SA_NAME : the email address for the user USER_EMAIL - REST The serviceAccounts.create method creates a service account Before using any of the request data, make the following replacements: : Your Google Cloud project ID. Project IDs are alphanumeric strings, like PROJECT_ID my-project : The alphanumeric ID of your service account.

If you delete the default App Engine and Compute Engine service accounts, the instances will no longer have access to resources in the project Delete with caution; make sure your critical applications are no longer using a service account before deleting it. If you're not sure whether a service account is being used, we recommend disabling the service account before deleting it. Disabled service accounts can be easily re-enabled if they are still in use If you delete a service account, then create a new service account with the same name, the new service account is treated as a separate identity; it does not inherit the roles granted to the deleted service account. In contrast, when you delete a service account, then undelete it, the service account's identity does not change, and the service account retains its roles When a service account is deleted, its role bindings are not immediately removed; they are automatically purged from the system after a maximum of 60 days.

You can usually undelete a deleted service account if it meets these criteria: The service account was deleted less than 30 days ago After 30 days, IAM permanently removes the service account. Google Cloud cannot recover the service account after it is permanently removed, even if you file a support request There is no existing service account with the same name as the deleted service account For example, suppose that you accidentally delete the service account [email protected]. You still need a service account with that name, so you create a new service account with the same name, [email protected] The new service account does not inherit the permissions of the deleted service account. In effect, it is completely separate from the deleted service account. However, you cannot undelete the original service account, because the new service account has the same name To address this issue, delete the new service account, then try to undelete the original service account If you are not able to undelete the service account, you can create a new service account with the same name; revoke all of the roles from the deleted service account; and grant the same roles to the new service account. For details, see Policies with deleted principals Finding a deleted service account's numeric ID When you undelete a service account, you must provide its numeric ID. The numeric ID is a 21-digit number, such as 123456789012345678901, that uniquely identifies the service account. For example, if you delete a service account, then create a new service account with the same name, the original service account and the new service account will have different numeric IDs If you know that a binding in an allow policy includes the deleted service account, you can get the allow policy, then find the numeric ID in the allow policy. The numeric ID is appended to the name of the deleted service account. For example, in this allow policy, the numeric ID for the deleted service account is 123456789012345678901: { "version": 1, "etag": "BwUjMhCsNvY "bindings": [ { "members": [ "deleted:serviceAccount:[email protected]?uid=123456789012345678901 "role": "roles/iam.serviceAccountUser" }, ] } Numeric IDs are only appended to the names of deleted principals Alternatively, you can search your audit logs for the DeleteServiceAccount operation that deleted the service account: In the Google Cloud console, go to the Logs explorerpage In the query editor, enter the following query, replacing with the email address of your service account (for example, SERVICE_ACCOUNT_EMAIL [email protected]): resource.type="service_account" resource.labels.email_id=" SERVICE_ACCOUNT_EMAIL" "DeleteServiceAccount" If the service account was deleted more than an hour ago, click Last 1 hour, select a longer period of time from the drop-down list, then click Apply Click Run query. The Logs Explorer displays the DeleteServiceAccountoperations that affected service accounts with the name you specified Find and note the numeric ID of the deleted service account by doing one of the following: If the search results include only one DeleteServiceAccountoperation, find the numeric ID in the Unique IDfield of the Log fieldspane If the search results show more than one log, do the following: Find the correct log entry. To find the correct log entry, click theexpander arrow next to a log entry. Review the details of the log entry and determine whether the log entry shows the operation that you want to undo. Repeat this process until you find the correct log entry In the correct log entry, locate the service account's numeric ID. To locate the numeric ID, expand the log entry's protoPayloadfield, then find the resourceNamefield The numeric ID is everything after serviceAccountsin the resourceNamefield - - Undeleting the service account by numeric ID After you find the numeric ID for the deleted service account, you can try to undelete the service account gcloud CLI Execute the gcloud beta iam service-accounts undelete command to undelete a service account Command: gcloud beta iam service-accounts undelete ACCOUNT_ID Output: restoredAccount: email: SA_NAME@ PROJECT_ID.iam.gserviceaccount.com etag: BwWWE7zpApg= name: projects/ PROJECT_ID/serviceAccounts/ SA_NAME@ PROJECT_ID.iam.gserviceaccount.com oauth2ClientId: '123456789012345678901' projectId: PROJECT_IDuniqueId: ' ACCOUNT_ID' REST The serviceAccounts.undelete method restores a deleted service account Before using any of the request data, make the following replacements: : Your Google Cloud project ID.
