Amplify provides a client library that enables you to interact with backend resources such as Amplify Auth.

The quickest way to get started with Amplify Auth in your frontend application is with the Authenticator component, which provides a customizable UI and complete authentication flows.

To get started, you can use the signUp() API to create a new user in your backend:

The signUp API response will include a nextStep property, which can be used to determine if further action is required. It may return the following next steps:

CONFIRM_SIGN_UP - The sign up needs to be confirmed by collecting a code from the user and calling confirmSignUp.
DONE - The sign up process has been fully completed.
COMPLETE_AUTO_SIGN_IN - The sign up process needs to complete by invoking the autoSignIn API.

By default, each user that signs up remains in the unconfirmed status until they verify with a confirmation code that was sent to their email or phone number. The following are the default verification methods used when either phone or email are used as loginWith options.

Login option	User account verification channel
`phone`	Phone Number
`email`	Email
`email` and `phone`	Email

You can confirm the sign-up after receiving a confirmation code from the user:
