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).
