Help with iphone factory rest!!!!

I was gonna sell my iphone 8 but cant because I forgot my apple password so i cannot factory reset it... i cant recover my phone til feb 12 because my phone is off so i cant get a code to my trusted number. Is there anything else i can do?? Im in need of cash for bills so i need to sell it but i cant wait til feb 12th.. i thought i knew my apple password but i guess every password i try nothing works.. anything else to try? This is my first iphone and personally because of this I probably wont get another iphone again.. too complicated. Can anyone help at all?? Im so frustrated. Please and thanks!! I already tried calling apple and they say i have to wait til i can recover it on feb 12 which doesnt help because i need to reset it today!
