By default Amplify Auth is scaffolded with `email` as the default method for user sign-in.

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

export const auth = defineAuth({
  loginWith: {
    email: true,
  },
})
```

This will configure an `email` attribute that is required for sign-up and cannot be changed.
