Why I was asked to enter iPad password during activation of my iPhone?

[bj097]

I was activating my iPhone last night but found out that one of the step required me to enter my iPad password, or else I wouldn't be able to access something.

Yes, I HAD an iPad connected to my Apple ID, but I gave the iPad to my ex-wife a few years ago but I remember that I should have logged out from the device, I wasn't this careless.

During the step, it said I'd be able to reset the iPad password but something will be deleted or cleared (I forget). I do not want to clear important things she has saved but I don't want to call her about what's happening. Nevertheless, she isn't familiar with Apple things.

Now I really don't understand why when I am setting up my new iPhone with my one and only one Apple ID, it will come to ask me the 4-digit password of my old iPad

My question is- If I don't reset the password of iPAD (because I don't want to delete / clear things if she is still using), but will she be able to find out pictures / videos or other activities of my device? I've reset the password of my Apple ID

If person has a different Apple ID than you and doesn’t know yours, then they won’t be able to access any of your iCloud stuff.
Every so often, iOS will prompt a user to change its passcode. You can keep ignoring it, but it’ll nag you forever.
So just change it and when things have calmed down (no more nag screens) change it back to the original if you want.

Your old iPad must be registered as a trusted device- that’s why you’re being promted to enter its passcode to set up a new iPhone with your AID.
There’s a setting somewhere that lets you designate which device is the trusted device. It’s all part of 2 factor security.

I have never ever seen iOS prompt me to change my passcode.

I have never ever seen iOS prompt me to change my passcode.

Vanilla iOS will never prompt for a passcode change. But some devices are managed by IT departments. Those will prompt for passcode changes according to IT policy.

OK.
I am not certain but I believe that my old iPad has been registered as a trusted device.

I'm also not certain but I remember that I logged out the old iPad

Fact is I have now changed the password of my Apple ID

In this case
1. Could my further activity be seen by the user of my iPad? Whether or not I logged out
2. I no longer see my old iPad in the list of App store but why it still asks me about the 4-digit iPad passcode
