With Amazon Cognito user pools, you can enable your web and mobile app users to sign up and sign in. You can change passwords for authenticated users and initiate forgotten password flows for unauthenticated users. The following section provides setup information and examples so you can use the Amazon Cognito Identity Provider to retrieve and update user pool profiles. These instructions are written for Android application development in Android Studio.
To get started see AWS Mobile SDK for Android and the Mobile SDK for Android documentation.
If you are a React Native developer then add user pools to your React Native applications with the AWS Amplify Library for React Native which includes the Amazon Cognito Identity Provider. For more information see Set Up the AWS Amplify Library for React Native. See also AWS Amplify Library Authentication Guide.
