Step 5. Install an Amazon Cognito User Pools SDK

Amazon Cognito offers two user pool SDKs, which complement each other.

The Amazon Cognito Identity SDK is the core user pools library. Install it to interact with the user management and authentication functions in the Amazon Cognito User Pools API.

The Amazon Cognito Auth SDK leverages the built-in hosted UI webpages. Install it to add webpages to your app for the following: sign-up, sign-in, confirmation, multi-factor authentication (MFA), and sign-out.
