AWS Cognito: How to prevent collection of phone number?

Question

I have a React app with AWS Amplify integration. When adding auth via Cognito, I do not want to collect phone numbers when signing up people, but I cannot change the settings of the user pool (since it has been created automatically in the amplify add auth process.

How can I prevent phone number collection?

Answer 1

Run:

amplify add auth

Next, in your generated -cloudformation-template.yml in the directory amplify/backend/auth// make sure that you have the following:

Schema:
  - Name: phone_number
    Required: false

This will make the phone_number optional.
