How do I change my account to an adult account?

Hi,Zaiden! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Unfortunately you can not do that

You need to wait until the account "turns" into an adult by itself according to the initial birth date. This is to avoid actual childs changing the birth date.

It is very important to set the birth date right the first time

Hello Cody,my name is Marvina, I will be happy to help you.

To switch to an adult account on Xbox, you must first be at least 18 years old. If you are 18 years old or older, you can follow these steps:

Sign in to your Xbox account on a computer or in the Xbox app.

Click your profile photo and select "Account Information."

Scroll down to the "Personal Information" section and click on "Date of Birth."

Enter your current date of birth and click "Save."

You will receive a confirmation email. Click the link in the email to complete the update process.

Once the update process is complete, you will be able to access all features of the adult account.

If you've tried changing your date of birth in your personalization settings and you still have child restrictions, you may need to contact Xbox Support.

They can help you complete the update process.

These are basic solutions to these problems, but they can lead to a solution, remember that this is a public forum where we are players like you who want to help, good luck and happy day.

Sincerely,
Marvina.

When I made the account I was a child. How do I change it to an adults account then?

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

If you're trying to access the privacy page to change your account settings but you can't, it means your account is a child's account and you can't change it.
You will need an adult within a family group to change your account's privacy settings.

An organiser in an Xbox family group can manage settings for members who are in the family group. Kids can only see (and not manage) their own settings.

To learn more about family group roles, see:

   Note Because you’re accessing sensitive info, you may have to enter your password or passkey.

6. Review the current settings and update any that you want to change, and then select Submit to save the changes.
   
   Note You must select Submit at the bottom of the page before leaving or switching to another tab. If you don't submit the changes before you move to the other tab, your changes won't be saved.
   
7. Have the member sign in and then sign out of their account on the console to make sure the changes take effect.
   

You can't.Once the date of birth is entered when creating your account it can not be changed.

You have to wait until the DOB on the account is 18 years old.
