Dear Sir/Madam,
I had iPhone 6 plus 3 years ago but now I bought 13 promax. Unfortunately, I don't remember the 6 Plus passcode. Now I can log in to the site with my old Apple ID, but when I log in to my iPhone, after passing the path, it asks me for the old passcode, which I don' remember. Please help.
iPhone 13 Pro Max
