Well, I still can't see it. How DO I get rid of the passcode?
This thread is from 2013, of course. Now it's 2015, my new iPhone 5c has iOS 9.1, and there is no "Passcode Lock"" under "General". Maybe there was back when this thread was started?
When setting up the phone, I decided to use a passcode, and entered one. Yes, I still remember it and use it. But I've changed my mind and would like to get rid of it.
It's between Sounds and Battery, but not in General. On my iPhone, it's "Touch ID & Passcode":
Tap it, enter your passcode, then scroll down to "Turn Passcode Off". Tap this as well. Then select "Turn off" on the following popup. You'll have to enter your passcode once more, and then it should be disabled.
