# Gerenciar chaves de acesso do IAM usando um AWS SDK O exemplo de código a seguir mostra como gerenciar chaves de acesso. **Atenção** Para evitar riscos de segurança, não use usuários do IAM para autenticação ao desenvolver software com propósito específico ou trabalhar com dados reais. Em vez disso, use federação com um provedor de identidade, como [Centro de Identidade do AWS IAM](https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html). + Criar e listar chaves de acesso. + Descobrir quando e como a chave de acesso foi usada pela última vez. + Atualizar e excluir chaves de acesso. ------ #### [ Python ] **SDK para Python (Boto3).** Há mais no GitHub. Encontre o exemplo completo e saiba como configurar e executar no [AWSCode Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/python/example_code/iam#code-examples).
