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:
-
Using Amazon Cognito Identity to authenticate users and supply credentials
-
Using web federated identity
-
Hard coded in the script
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.
