an ID cannot be changed into an alias but you can create an alias of that ID or you may choose to display your name instead of the real ID when entering games. to make an alias, log in with your ID and correct password, then click %26quot;My Account%26quot; or %26quot;My Account Info%26quot;. in your account info page, create/edit profiles. the page will be displayed for you to create an aliasses as you like. or on messenger, click your name(avatar) if you have and click at the bottom %26quot;Create/Edit Profile%26quot;. same process to do when creating an alias.
