Need to be able to let security passcode have five spaces not four

I have the 6s which is a problem when I want my notes to be protected because in your security passcode it only has four spaces not 6 for my phone and other phones that allow the your passcode to have 6 spaces. What you should do is not allow any phones that have less then 6 spaces in their passcode no to be able to update the app but to still have the features in the latest update and to update any phones that have more than 4 passcode spaces.
