i know i passcode, but i want delete it, i want a NONE PASSCODE IPHONE

I understand that you would like to remove the passcode from your iPhone and use your iPhone without a passcode. When you do this, then you will not be able to use Face ID either. Just wanted you to know that.

Open Settings ➔ Face ID and Passcode ➔ Turn Passcode OFF.
