I'm not sure why you've got downvoted, but I can confirm, that I'm using Macbook, iPhone, iPad and I very rarely have to enter iCloud password. I don't even remember last time I did it. I'm not reinstalling stuff or whatever, usually I'm working with programs I'm using and only password I'm constantly typing is password from locked computer or pincode for phone (and even those could be eliminated with modern touch buttons, I think).
Regarding the downvotes; I suspect it was the holier-than-thou tone delivering a blinkered refusal to accept someone else's reported experience, all prefaced by a cheap sneer.
I generally find that this forum has a higher than usual tolerance for unconventional perspectives, but takes a very dim view of poor manners. Unlike other places that seem to reward and even celebrate bad behaviour and low standards of discussion. This is a major reason I contribute here and basically nowhere else.
It's the anti Apple sentiment on HN. Nothing Apple is good anymore. But yeah, I can't remember either the last time I had to enter the iCloud password.
