Microsoft, Sony, and Steam accounts can be linked to a Call of Duty profile from the Overview section of your Call of Duty profile. If you do not have a Call of Duty profile, you can create a free one.
Follow these steps to link an account:
Please note: A Call of Duty profile may only have one account linked per manufacturer.
If you need to change your account, or you want to unlink an account, simply select the account you want to change or unlink, then select Continue.
Please note: Unlinking and relinking accounts can cause corruption with Season Pass, DLC, Micro DLC items, or other entitlements applied to your accounts. Please avoid any unnecessary unlinking and relinking of accounts.
