How to keep child from logging into family organizer account on Xbox?

Hi, ScottChalker! Thank you for reaching out.
I'm AJ, an Independent Advisor for the Xbox Community.

May I ask if you have already tried changing your account's sign-in and security preferences? like this:

- On the console, sign in to your account.
- While on your account, go to Settings > Account > Sign-in, Security & PIN.
- Select "Change my sign-in & security preferences

* Selecting "Ask for my PIN" should make it so your PIN is asked for whenever your account tries to sign in.

* Selecting "Lock it down" should make it so your password is asked for whenever your account tries to sign in.

I'll be looking forward to your reply.
Best regards.

That's correct as they are child accounts and you mentioned they haven't been added to the family, in the account that manage to enter the privacy settings leave the current family even if there no one else in that family, after this log out of the family site and restart the browser

Once done with that create the family again, with that account being the organizer, and add the child accounts, remember that child accounts can't be organizer they must be added as childs, and check each account on the family site prior to this to verify that they aren't linked to other families

Child accounts can't be the account information about other members, only family organizers, the organizer must log in the site with all the available accounts he has to confirm which account has the child added

Good evening

Family Organizer Account: Ensure that you are logged in with the Microsoft account that serves as the Family Organizer. Only the Family Organizer has the authority to manage family settings.

Family Safety Website: Visit the Microsoft Family Safety website (https://account.microsoft.com/family/) and sign in with your Family Organizer account.

Account Management: Locate your child's account within the family group and click on it. Look for options related to account management or permissions.

Admin Privileges: Review the settings and permissions assigned to your child's account. There might be an option to grant administrative privileges or elevate their account to the administrator level.

Are you using a child's account?

If yes, have you tried to ask the Family Organizer to log in and change your privacy settings?
