What is an Apple ID?
An Apple ID is the personal account you use to access Apple services like the App Store, iTunes Store, iCloud, iMessage, the Apple Online Store, FaceTime, and more. It includes the email address and password you use to sign in, as well as all the contact, payment, and security details that you’ll use across Apple services.
Sign in to your Apple ID on a new device
Sign in with your Apple ID when you first set up your device to access all Apple services. You can also sign in to your Apple ID later in Settings.Set up your device with your Apple ID
Share content with your family
Want to share content with friends and family? Don’t share your Apple ID — just set up Family Sharing. This lets you share purchases, photos, a calendar, and more with members of your family across all of your devices.Set up Family Sharing
Changing your account information
It’s very important to keep your Apple ID secure. Only you should be able to change your password, make iTunes and App Store purchases, or sign in to services like iCloud, iMessage, and Find My iPhone.
If you’re going to sell or give away your device
Be sure to sign out of your Apple ID if you’re going to sell or give away your device.
