When to use this flow
If you wish to use KWS to handle sign-on by users under the legal age threshold, but a separate system to handle all other users, we recommend this flow.

About this flow

Use either the Access gate for kids or the Feature gate for kids to handle the kid’s sign-up and access to features.
If the user is above the age threshold:
Handle the sign-up flow using your own custom-built system. See Build your own custom authentication UI.
