No passcode is possible. I have it configured that way for a device I have mounted on the wall at home. But apple makes it difficult to do so, as in a lot of extra steps, warnings and reminders, not just initially but every single update too. They've made it inconvenient intentionally, which is good.

Really? I don’t spy on other people so I don’t know. But I know 6-digits passcode is the default and Apple makes it intentionally harder for people to switch to a shorter, I think it’s the norm. And if people are so lazy and lax with their security, what is the chance of changing 4-dits to a much more inconvenient password? Yes, old people cannot even use the soft keyboard without glasses!

In general, I don’t get the meaning of the article. Face-Id is so convenient and secure, 6-digits code is the norm. If people just follow the Apple instruction, they won’t need to worry about anything.
