It says my devices passcode is wrong when trying to reset my Apple ID

I’m trying to reset my Apple ID and it says to enter my devices passcode after entering my phone number, but whenever I do this it says the passcode is wrong. I know that it’s right because I enter this passcode to open my phone everyday. I tried to pick another device to enter the passcode for and I know it’s the correct password everytime I enter it in but it still says it’s wrong. What do I do?
