Why do i keep getting password required popup on my iphone?

Whenever you try to download an app from App Store or access iTunes, it will ask for password. If you're not trying to do anything and still it's popping every now and then, it means some app is trying to update automatically or trying to access App Store.

I used to continually get voicemail password pop ups if that is what that is. I didn't even know I had a password for that and was really confused why it kept popping up but I just called my provider and got the password so I could make the pop ups go away and be able to use my voicemail again.
