MacBook Pro wont accept my iPhone's lock screen passcode
i just got a new MacBook Pro, on macOS 13.5.1, and it keeps prompting me to update my Apple ID settings. I click into it and before I can proceed, I have to enter 3 passwords:
1) for my apple ID, which I get correct.
2) for my mac, which I get correct.
3) for my iPhone, which IS correct! But my Mac repeatedly tells me it is incorrect.
I have already covered the camera of my iPhone to force it to prompt for the 4-digit code, which i get correct and unlock my iPhone with. I have done this multiple times!! And when I go back into my Mac, it STILL says it isnt correct. I have tried clicking "don't know my password", which it then prompts me to pick another device, and my apple watch is not an option. So i cannot proceed!!
What am I doing wrong, if anything, and how do I proceed in order to update my apple ID settings?
MacBook Air, macOS 13.5
