I don't lock my phone at all. Never have. However, with the new iPhones that don't have a home button, I believe that Apple is forcing you to either use face unlock or a passcode. There is no choice to just leave it unlocked.
So, as soon as my iPhone 6s stops working, I will have to choose to: 1) Give in and use my face to unlock. 2) Use a dumb passcode like 000000. 3) Upgrade to the newest iPhone that still has a home button (I think iPhone 8) or 4) Become and Android user.
