# AWS SDK를 사용하여 IAM 액세스 키 관리
<a name="iam_example_iam_Scenario_ManageAccessKeys_section"></a>

다음 코드 예제에서는 액세스 키를 관리하는 방법을 보여줍니다.

**주의**  
보안 위험을 방지하려면 목적별 소프트웨어를 개발하거나 실제 데이터로 작업할 때 IAM 사용자를 인증에 사용하지 마세요. 대신 [AWS IAM Identity Center](https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html)과 같은 자격 증명 공급자를 통한 페더레이션을 사용하세요.
+ 액세스 키를 생성하고 나열합니다.
+ 액세스 키가 마지막으로 사용된 시기 및 방법을 조회합니다.
+ 액세스 키를 업데이트 및 삭제합니다.
