The way to confirm it isn’t a hack or fake is to pay attention to the way it looks. On my iPad it used the expected view that you get prompted with for entering your passcode to deal with FaceID or similar. That screen can’t be faked fully as it is a view only available to Apple for “system” prompts.I got something like that about a week or two ago and reluctantly entered it in hoping I wasn't enabling a hack, so thanks for confirming it was 100% legit!
My wife had this pop up soon after updating to 16.2 on her iPad Pro. once done she didn’t encounter it again. I’ve read posts from a few that they were caught in a loop, even after entering the correct passcode the notification remained even though they could use iCloud as usual. I’ve yet to encounter this on any device so I’m wondering if it is being triggered on a staggered basis. But I’ve activated 3 new devices this year so entering my iCloud password during that process may circumvent this if you've recently had occasion to enter the Apple ID.I had to do it on my iPhone and then, a few days later, on my Mac after updating to the latest software. It was slightly alarming but as LogicalApex said, it looked like it was using the secure system views and I am guessing it is to do with encryption. Be useful if there was some information from Apple on why it is required periodically.
You can choose Other Options for setting up a Passcode. I choose not to have one. I also choose not to have 2FA.
Yeah, I guess that's probably logical for lots of people.So don’t live like you. Got it.
I'm not sure where you live but in the USA cars get broken into all the time to take things like laptops and iPads. If you don't have a passcode they have access to everything on your Apple account. For you that might not be much so maybe it's OK. I know people who keep very little on their iPad because it's just to watch movies. I have so much stuff in my iCloud Drive and notes that it would be catastrophic. They would get bank account information, passwords, all my contacts to include addresses and dates of birth so they could do all kinds of scams on my friends and relatives.Yeah, I guess that's probably logical for lots of people.
But I just don't need the security, and don't want to be entering a passcode all the time. If I can't keep my iPad with me when I leave my house, it stays behind. So, on an airplane, it's in my carry-on. On a road trip, it stays locked in the car when I'm not in my hotel room. I'm vulnerable there if the car is stolen, but then I've got a bigger problem.
