Have to use my email and password to sign into my child’s Xbox profile on Xbox one.

Hello Raelik, try going to Settings/Account/Family Setting on your console and/or Setting/Account/Content restrictions for parental settings on your console

Hello TGAM,

Thank you for posting here on the Xbox forums. If the email and password is bringing up a different profile, then the email they are using is incorrect. Every profile is attached to
one sign in email. You can sign into your
microsoft account here, then look at your family to view the emails to your child's sign in email.

Hope this helps

I created an XBOX live subscription on the PC, with my email.

Now i want to sign into XBOX live on my XBOX profile, using same EMAIL.

I don't want a new profile, i want to keep using my old one.

With this account's email/password for XBL.

Hi,

just add the two that aren't on the system by signing in using their email and password.

Scroll left at home screen -> profiles -> add and manage -> add new -> Sign in using the email and password you used to sign up the child accounts you need to do this twice.

note: don't press A on get a new account.

Have a great one

You can use your Xbox One console to find your child’s Microsoft account email address if either of these conditions apply:

• You can sign in to your own profile on the Xbox One (see Solution 1 below).
  
• Your child has a saved profile on the Xbox One (see Solution 2 below).
  

If neither of these solutions work for you, return to the previous step using
Your Steps on the right side of this page. Then, select another method of finding your child’s Microsoft account email address.

Solution 1: Sign in to the Xbox One using your own profile

1. Sign in to your profile on the Xbox One console.
2. Press the Xbox button
   to open the guide.
3. Select System.
4. Select Settings.
5. Select Account.
6. On the Account settings screen, select Family.
7. Select your child’s profile.
8. Select Add to this Xbox.
   
   Note If your child’s profile is already saved on your Xbox One console, you will not see the option to add them. If this is the case, go to
   Solution 2 below.
9. The next screen will show your child’s Microsoft account. If you know your child’s password, enter it now to complete the sign in process. (If you need help with a forgotten password, select
   Continue below.)

Solution 2: Sign in to the Xbox One using your child’s saved profile

1. Sign in to your child’s saved profile on the Xbox One.
2. Press the Xbox button
   to open the guide.
3. Select System.
4. Select All settings.
5. Select Account.
6. On the Account settings screen, select Sign-in, security & passkey.
   
7. On the Sign-in, security & passkey screen you will see your child’s email address displayed. This is the email address your child uses to sign into their Microsoft account.
