Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Setting Credentials in a Web Browser

There are several ways to supply your credentials to the SDK from browser scripts. Some of these are more secure and others afford greater convenience while developing a script. Here are the ways you can supply your credentials in order of recommendation:

  1. Using Amazon Cognito Identity to authenticate users and supply credentials

  2. Using web federated identity

  3. Hard coded in the script

Warning

We do not recommend hard coding your Amazon credentials in your scripts. Hard coding credentials poses a risk of exposing your access key ID and secret access key.
