I'd like to know this too. I have to enter it on my Mac from time to time (it seems kind of random, I think) but I have to it EVERY time on my iPhone. Annoying indeed.
I've found that sometimes I don't have to enter my password again if I've just a minute ago installed an app. Otherwise I usually have to enter it every time and there are no options.
