My passwords leaked/shared from my iCloud account to another (wife's).
Hello. We have couple of devices in our family: macs, iPads, iPhones. Macs are usually shared (everyone has account), mobile devices are "inherited".
I noticed that my iCloud passwords and credit cards are visible on wife's account. Everywhere: iPad, iPhone, Mac. She has her own iCloud account and always uses it on device.
How come could the data leaked? I was wondering what happens when I give my iPhone to someone, should everything sensitive be erase when I log out of iCloud?
iPad mini, iOS 12
