Adding Authentication

Next, let’s update the app to add authentication.

To add the authentication service, we can use the following command:

$ amplify add auth

? Do you want to use default authentication and security configuration?: Default configuration 
? How do you want users to be able to sign in when using your Cognito User Pool?: Username
? Do you want to configure advanced settings?: No, I am done.   

To deploy the authentication service, you can run the push command:

$ amplify push

? Are you sure you want to continue? Yes

When this step completes you will have authentication services set up in Amazon Cognito. To see more information, you can run the console command:

$ amplify console auth

Using service: Cognito, provided by: awscloudformation
