Katie bought an iPhone from Amazon, and it keeps asking her for an old credit card number for her Apple ID. She was able to activate it and make calls, but she can't really do anything else. Leo says you should be able to change or add a payment method with that existing Apple ID. Just click on your name and then the payment information. If you can't do that, then you can try 1-800-MyApple or iForgot.com to reset your password. Leo also suggests making an appointment with the Apple Store and taking to a Genius about resetting your Apple password. They have the ability.
Your Apple ID is an account used to unify your obtained media/apps/content amongst your Apple devices. You do not need to create a new one for each new Apple machine you buy. Ideally, you'll keep one personal Apple ID for life. If you accidentally made a new ID, despite having all of your purchased content on an old ID, just don't use the new one. Log out in System Preferences, then log into your more fully-loaded Apple ID.
Robert recently bought a new Mac and created a second Apple ID. How can he merge his two Apple IDs together? Leo says he can't. Apple won't allow it. But that's OK, all he needs to do is log out of the new Apple ID, and log into the old one. Just use it for everything.
Corrine is having issues with her Apple ID. Leo says that her iCloud account and her iTunes account can be different. Or she could have them be the same. She'll then need to have a password that goes with it. All of her app and website passwords can be kept in the Apple Keychain, but she'll have to be on the same account in order for it to work across her devices. She'll have to be sure to go into her iCloud and Keychain settings and make sure they're all turned on.
Jack is in the banking industry and he recently left his job. But when he did, he lost his Apple ID and they remote wiped his phone. Will he have trouble switching it over to a new Apple ID and will he lose all the apps, music, etc. that he bought? Leo says that Jack should be able to go to the Apple ID and change the email associated with it. They'll look for confirmation on the old email, though. He'll need to also log into the old Apple ID account and turn off Find My iPhone and back up to iCloud.
Burt has a Motorola Max mobile device and an iPad. He got a notification to update his security and contact list on his phone, but the iPad gave him a notification that his Google password had changed without his knowledge. Leo says that's worrisome. It sounds like someone may have hacked his Google account. Leo advises going to iCloud.com to see if he can log in. If he can, then his AppleID is likely secure. But Leo advises changing the password again to verify everything.
On Sunday's Tech Guy show, Jason Snell of SixColors.com was filling in for Leo Laporte and shared a tip about managing your Apple ID. Not many people are aware that Apple has a page for doing this at appleid.apple.com. You can change the email addresses and phone numbers associated with your account, add/change your trusted phone number for two factor authentication, change your Apple ID password, change payment and shipping info, and more.
Dan has 2 factor authentication, and he keeps getting a notification that someone is trying to log in using his Apple ID and he gets knocked off his sign in. Can he change his login ID to eliminate it or will he lose all his purchases? Jason says that he's had that issue and it's very annoying.
Clyde and his wife both have iPhone 5Cs on AT&T, but they get each other's text messages, and their daughter gets them too. Leo says they share text messages because they all are using the same Apple ID. They'll need to create a separate account for each of them. They won't lose their ability to share apps either, because Apple has Family Sharing.
Clyde is also getting a Blue Screen of Death with a DPC error. Leo says that's usually referring to a problem with the SSD Device driver. It's also due to an old operating system, so upgrading to Windows 10 should fix it.
Dan was using his iPhone 5s and he got a message that someone is trying to sign into a device using his Apple ID. Apple says that they don't send out messages like that. Leo says that isn't really accurate as he's gotten those as well. Any time you sign into a new device, you get that message. If it comes with a suggestion to change the password, however, then that could be a ploy to steal his Apple ID from a browser. He should never do that.
