Apple Account passcode issue after factory reset and backup restore

I phone reset at Apple Store to factory settings.

I tried to reinstall from a backup from account .

I was then asked to create a new passcode, which I did.

I was then asked for the old passcode. I entered it however I was told that it was not recognized.

I don’t know why that happened but then it asked for the passcode of my IPAD which I entered and it was excepted.

my iPad isn’t associated with the account.

it seems as if the password app doesn’t work.

But I could login to post this question
