How to i get past the blue screen that says select your account without a password?

Question

I saw something on the internet that said it would boost my performance if I were to type in msconfig and when I did it, it said I needed to restart my laptop for the changes (I change the processors to 8) and now I have this screen. I know the password but the thing is I can’t type it in because one of the letters I need to put in is broken on my keyboard so I’m stuck with that screen and I don’t know how to get past it
