Quote:Users of any Apple device must have an Apple ID. It’s a kind of digital passport for journeying in Appleland. You need an Apple ID to enter, and it gives you certain rights. And it should be treated like a passport: Don’t lend it to anyone, and don’t borrow anyone else’s.

The first point is obvious. Giving someone your Apple ID means losing access to your own devices, your data, your subscriptions and so on. But questions often arise about why you should never enter someone else’s Apple ID on your iPhone or iPad. Let’s use Marcie’s story as a case study.

Next came the question of price. The phone was in good shape, so she decided to aim high. She hadn’t spent a year blowing dust off it for nothing. And not a single scratch! Sure, it might take a while to find a buyer, but Marcie was in no hurry.

To her surprise, one appeared the very next day. A polite woman wrote that her husband really wanted to buy the iPhone, but he was terribly busy and couldn’t drop by until the end of the week. But he really liked the fact that the device was in perfect condition, so he wanted to make an advance payment and pick it up later. To check that the phone really was A-OK, the woman asked Marcie to enter her husband’s Apple ID into the device. If it worked, she would transfer the prepayment right there and then.
