Account details

Go to Settings then "emails+accounts" and it will be the first account listed, under the name Microsoft Account.

You will need to change your password.

Hi, the best thing to do is to change your password, and remove his device as a trusted device, this in turn will remove all your trusted devices, but you can re log in on the ones you want to use anyway. You can change your password and remove trusted
devices on
account.microsoft.com under the security section

Hello Wright,

If unsuccessful with the account recovery. You can request a call from support. When you give them the gamer tag they will locate the account. If you can verify the account, they can give you details. It is worth a try never know may get lucky and are able
to verify the account.

When you go to Contact Us to get it to request a chat follow these steps:

• Step 1 ----select Xbox One
  
• Step 2 ----select see other options then subscription changes
  
• Step 3-----select show contact options
  
  Step 4 ----select request call from support
  

Once they call explain the issue and they will be able to help you. Note that these options regularly change so just keep selecting something that gives request a call from support as a contact option.



Hope this helps.



Thanks,

Brad
