Providing AWS Credentials in the AWS SDK for

Java

To make requests to Amazon Web Services, you will need to supply AWS credentials to the SDK for

Java.There are a number of ways to do this:

• Use the default credential provider chain (recommended)

• Use a specific credential provider or provider chain (or create your own).

• Supply the credentials yourself. These can be either root account credentials, IAM credentials or

temporary credentials retrieved from AWS STS.

Important

It is strongly recommended, from a security standpoint, that you use IAM users instead of the

root account for AWS access. For more information, see IAM Best Practices in the AWS Identity

and Access Management User Guide.

This topic provides information about how to load credentials for AWS using the SDK for Java.
