You’re asked to update your account when downloading your Xbox Live profile
We may ask you to update the information for your Microsoft account when you download your Xbox Live profile on your console. This is because some information was not included when you created your account.
You may be asked to provide the following when you sign in on your console:
First and last name: This lets us personalize your experience on Xbox and other Microsoft services. It also helps us verify your identity if your account is compromised, or if you forget your password.
Date of birth (DOB): Xbox has a global policy that users under the age of 18 must have parental permission to create an account. Additionally, we must comply with child privacy requirements in the United States and South Korea. Therefore, we require a date of birth for all accounts.
Security information: When you make sensitive financial or credential changes to your account, we need to make sure that it’s you making the changes. To do this, we’ll send you a security code by phone or email.
When prompted to update your Microsoft account information while using your Xbox One, follow the instructions displayed on your console. Additionally, you can sign in to your Microsoft account at account.microsoft.com to complete the necessary account updates. See the instructions below.
Here’s how to update your Microsoft account information for Xbox 360:

For child accounts, in some regions
If the birthdate on a Microsoft account says that it belongs to a child, there are different steps to take in regions such as the United States of America and the Republic of Korea, and other regions that regulate what children can do online.
