Describe the feature

Amazon Cognito announced support for email-based multifactor with one-time passwords

// amplify/auth/resource.ts
import { defineAuth } from "@aws-amplify/backend"

export const auth = defineAuth({
  loginWith: {
    email: true,
  },
  multifactor: {
    mode: "REQUIRED",
    email: true,
    // or
    // email: {
    //   subject: "verify yourself",
    //   message: (code) => `here's your code: ${code}`
    // }
  },
})

Is there any documentation available for Amplify Gen1 customers?

We would like to enable Email OTP in our Amplify Gen1 App possibly by using an override until it's available?

Also will this feature be supported in Amplify Gen1 or just Gen2 planned?
