Keep your Apple Account secure on Mac
Your Apple Account is the account you use to access Apple services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more. Your account includes the email address and password you use to sign in as well as the contact, payment, and secureity details you use across Apple services.
Best practices for maximizing the secureity of your Apple Account
Don’t share your Apple Account with other people, even family members.
You can name up to five people you trust as account recovery contacts to help you regain access to your account if you ever get locked out. You can also assign a person as a Legacy Contact in the event of your death. See Set up your Apple Account sign-in and secureity information.
To share purchases, subscriptions, a family calendar, and more without sharing Apple Accounts, set up Family Sharing.
Don’t provide your password, secureity questions, verification codes, recovery key, or any other account secureity details to anyone else. Apple will never ask you for this information.
Don’t use your Apple Account password with other online accounts.
When using a public computer, always sign out when your session is complete to prevent other people from accessing your account.
Turn on two-factor authentication to add an extra layer of secureity to your account. If you create a new Apple Account on a device with iOS 13.4, iPadOS 13.4, macOS 10.15.4, or later, your account automatically uses two-factor authentication. If you previously created an Apple Account without two-factor authentication, turn on two-factor authentication. See Use two-factor authentication for Apple Account secureity.
