How can I allow my child to create accounts on other apps
using their apple IDs so they can save their work across devices?

Original Title: How can I allow my child to create accounts using their own AppleID? And please do not post directions to creating an Apple ID for my child, that is not helpful.
I am not clear what you mean by using other apps. If you mean what the Sign In With Apple service offers then note the age limits.

"When you see a Sign in with Apple button on a participating app or website, it means you can set up an account using your Apple ID. No need to use a social media account, fill out forms, or choose another new password."
"Sign in with Apple is not available for children under 13 years old. This age may vary by country or region. This age restriction doesn't apply to Managed Apple IDs."
