I don't remember my Apple ID password

i got a new phone about an hour ago and i have a second email account that i use for everything. i made it a long time ago so i dont remember the password. i tried so many times it locked and to unlock it was sending it to an email i cannot get in on my new phone, i also tried my security questions and my birthdays is wrong which im not sure how either. but this email is connected to all my stuff and i have no clue what to do

and last used was on my old phone iphone XR
