Is there a simple way to remove a passcode from iphone 6, I have my passcode

In Settings/Touch ID & Passcode you can turn off the Pass Code:

However, you'll need the passcode to access this setting to turn it off and again to turn it back on if so desired. Do don't forget the passcode.

You'll also need the passcode whenever you update the iOS on the phone.

Good info. It worked.
