Really important stuff is of course handled in other ways..
All you have to do is go to settings > passwords and enter the pin and there they all are.
Sao if you use this, have a really good iPhone pin!
iPhone PIN ? Say what now ?
Only fools use PINs.
iPhones have supported keyboard entry for passwords for a very very very very long time now. And more recently, TouchID and FaceID, of course.
You can also configure iOS to erase after n incorrect entries.
At this point in time, you get what you deserve if you still use numeric PINs.
Sometimes it’s preferable to pay the professionals, especially if you’re not an expert. I’ve recommended LastPass to my grandparents for years because it’s better than using their grandkids’ names as passwords everywhere.
