|Amazon S3 enables sending requests using temporary security credentials.||
In addition to using your AWS account and IAM user security credentials to send
authenticated requests to Amazon S3, you can now send requests using temporary
security credentials you obtain from AWS Identity and Access Management (IAM). You can use the AWS
Security Token Service API or the AWS SDK wrapper libraries to request these temporary
credentials from IAM. You can request these temporary security credentials for your own
use or hand them out to federated users and applications. This feature enables you to manage your users
outside AWS and provide them with temporary security credentials to access your AWS resources.
