How do I change the unlock passcode on my iPad mini?
I was just given an iPad. Turns out it is OLD, but it was given to me, so I can't complain. According to the "About" screen it is an iPad mini 2, running iOS 12.5.7. It was reset to "new" when I got it, so I set it up and got it working. I'd entered a password for the Unlock, which is turning out to be awkward, and I'd like to change it to a numeric code. I've googled this, and I get a lot of answers, none of which seem to be what I need. It isn't that I've forgotten anything. I know the code to get into it. I found one screen that I thought was it, but it turned out to be to change the Apple ID password, which isn't what I want. I just want to change the code to unlock the device. I know the current code, so I can provide that when it is called for, I just can't find the necessary screen to do this. Everything I find talks about looking for something marked "FaceID" or "Touch ID" reset, and this is an OLD device, it doesn't have TouchID or FaceID. Can someone help me to change the unlock code?
