I'm not an iOS user myself, but my mother has an iPad and iPhone, and I'm the family tech support (I've been a software engineer for almost 40 years).
Her iPhone frequently asks for her iCloud password. Shouldn't this be saved automatically in the settings, so she doesn't have to keep entering it?
She has the lock screen password disabled, does this prevent saving the iCloud password?
It also hasn't backed up to iCloud in months (I just did a manual backup). On the backup screen it says that it should backup automatically when it's plugged into a power source and locked. Does the lack of a lock screen password mean that it won't backup automatically, since it's never actually locked?
I just turned off the lock screen passcode on her iPad, is it going to start doing the same thing?
