Is there a way that I could set a PIN to prevent In-App Purchases on my Nexus 4 (like on my Nexus 7)? The only option I see is "Password". I don't like the idea of making a purchase for 30 mins without having to re-enter my password. I'd rather have it set to require a PIN for every purchase/IAP I make.
