: When you click "Login via Steam," a new window appears. It looks like a standard Windows pop-up, but it is actually just a layer of HTML/CSS inside the existing tab [3, 6].
: Password managers will not autofill credentials into these fake windows because they recognize the "window" is just a part of a malicious website [4].
