Hi, My friend had her iPhone stolen. It’s a 6 and she is logged into her iCloud and had a credit card on Apple play. She had Touch ID set up and a passcode too. We tried to go to iCloud.com and lock her phone but she has forgotten her security details. We phoned up Apple, but found no way into her account. Should she cancel her card? Or is it secure enough that someone won’t be able to get in? We’re worried that someone may be able to somehow get in and steal her details and information. Thanks.
