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.
Any time you set up a new device, make a purchase, or use any Apple service, you will be asked to sign in with your Apple ID and password. Once signed in you’ll have access to the service and all the personal information in your account.
Just one. Use the same Apple ID everywhere you sign in to ensure that all your Apple services and devices work together seamlessly and you can access your personal content from all your devices.
Your Apple ID should not be shared with anyone else. It provides access to personal information including contacts, photos, device backups, and more. Sharing your Apple ID with someone else means you are giving them access to all your personal content and may lead to confusion over who actually owns the account. To share iTunes & App Store purchases, photos, a calendar, and more with someone else, try Family Sharing, iCloud Photo Sharing, or other easy-to-use sharing features.
Security and privacy are very important to Apple and we provide a number of ways to secure your Apple ID and protect your privacy including strong passwords, two-factor authentication, and more. Learn more about security and your Apple ID.
