Weird Login screen

Sometimes when I press alt+f4 I get taken to a weird black screen which asks for my login & password, I assume it's because I misclick. The screen is just a black screen with grey text on it saying "cachyos-somethingsomethingsomething" and "cachyos login" which when entered into adds another line saying "cachyos password". I have tried multiple times to enter my login but I haven't got it right once, which is why I want a fix. Apologies if i haven't been very clear and my description is probably inaccurate somewhat
