How to update my wrong birthdate

If you’re still a child or minor under a family group you may not be able to manage it. It will be the organizer that can manage it. Ask your parents to do so by them signing in to https://account.microsoft.com/family using their account where your account is added as a “member”

Can you have any guide for it? As in a family group or not, i didn't see any options to change it.

The root cause maybe the birthdate is setting up by something as default, which causing i couldn't change at now.

This may mean that you're on a family group which an organizer or your parent is the only one that can manage it.

Hi,

It didn't work as i tried before.

When i clicked "Edit profile info", my birthdate is grayed out, from outside, the page is displaying "Your date of birth is used for account safety setting", maybe it is forced for some securities contraint
