OP, you login with login name, you don't login with display name.
Login names you can't change, nor alter, it's a forever fixed login name, and only one person can have said login name, that the only name you use for login on Steam either by browser, app, or client.
Display name is just what it is, for display, you can change it many times, whenever, and does not matter, as anyone can have the name.
