# Managing Amazon ECS account settings using the AWS CLI
<a name="account-setting-management-cli"></a>

You can manage your account settings using the Amazon ECS API, AWS CLI or SDKs. The `dualStackIPv6`, `fargateFIPSMode`, `fargateTaskRetirementWaitPeriod` and the `fargateEventWindows` account settings can only be viewed or changed using those tools.

**Note**  
You can use dual-stack service endpoints to interact with Amazon ECS from the AWS CLI, SDKs, and the Amazon ECS API over both IPv4 and IPv6. For more information, see [Using Amazon ECS dual-stack endpoints](dual-stack-endpoint.md).

For information about the available API actions for task definitions see [Account setting actions](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/OperationList-query-account.html) in the *Amazon Elastic Container Service API Reference*.

Use one of the following commands to modify the default account setting for all users or roles on your account. These changes apply to the entire AWS account unless a user or role explicitly overrides these settings for themselves.
+ [put-account-setting-default](https://docs.aws.amazon.com/cli/latest/reference/ecs/put-account-setting-default.html) (AWS CLI)

  ```
  aws ecs put-account-setting-default --name serviceLongArnFormat --value enabled --region us-east-2
  ```

  You can also use this command to modify other account settings. To do this, replace the `name` parameter with the corresponding account setting.
