The AWS SDK for JavaScript v2 has reached end-of-support. We recommend that you migrate to [AWS SDK for JavaScript v3](https://docs.aws.amazon.com//sdk-for-javascript/v3/developer-guide/). For additional details and information on how to migrate, please refer to this [announcement](https://aws.amazon.com/blogs//developer/announcing-end-of-support-for-aws-sdk-for-javascript-v2/).

# Loading Credentials in Node.js from Environment Variables
<a name="loading-node-credentials-environment"></a>

The SDK automatically detects AWS credentials set as variables in your environment and uses them for SDK requests, eliminating the need to manage credentials in your application. The environment variables that you set to provide your credentials are:
+ `AWS_ACCESS_KEY_ID`
+ `AWS_SECRET_ACCESS_KEY`
+ `AWS_SESSION_TOKEN`

For more details on setting environment variables, see [Environment variables support](https://docs.aws.amazon.com/sdkref/latest/guide/environment-variables.html) in the *AWS SDKs and Tools Reference Guide*.
