How do I keep my friend from using my Apple ID on her iphone?

Me and my friend both have iphones. I let her use my apple id because hers didn't work. I don't trust her. If i change the password on my apple id will she still be able to use it?

When you change your password, it will NOT log your friend out, BUT it will keep nagging her to type in the new password.

No. She will need the new password

No. You should change it without mentioning it.

Changing the password should stop her from getting any further access to your apple id account.

Why does she need to use your Apple ID, this only allows her access to your account, NOT hers. So if she wants to snoop into your iCloud account, she can. If she needs a new Apple ID she can create one at any time, she will lose access to any paid apps she has until she re registers them with the new Apple ID. So again, why does she need to use your Apple ID again?

And you can change YOUR password any time that you want to. And no once you do that she will not be able to gain access to your account. Just make sure that BEFORE you change the password, that you remove ALL devices from iCloud access that and the APPLE ID that are NOT YOURS.

Master Of Puppets has it right, but you can at the same time that you change your ID remove her iPhone from your listed devices.

Remember that all devices using your ID are listed on YOUR account. I would say that she has no account of her own (and probably never did have one of her own) since Apple allows being listed on one account ONLY.

She can start her own account if her iPhone is actually her iPhone and not a previously stolen/lost/sold iPhone that was never shut off by the original owner. If the phone company (and Apple) are not notified of a stolen/lost/sold iPhone, it is not shut off in the data base and thus can still be reactivated on a new phone number as long as there's an active Apple ID available to use with it.

Not only does leaving her in your account allow her access to your devices, but also allows her to use the Apple services at YOUR expense for downloading anything she wishes from the Apple Store.

No

Password change

Change the pasword and sign out of all devices! And tell her you forgot its pasword
