Set credentials in a web browser - AWS SDK for JavaScript

The AWS SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the AWS SDK for JavaScript version 3 (V3).

Set 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

Warning

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