Your Apple ID is your personal account for the entire Apple universe .
With one account , you can access all of Apple's products and services like icloud , the App store and a lot more that means you'll have the best experience with your Apple devices and services .
If you use just one Apple ID and don't share it with anyone else .
Why do you need an Apple ID ?
When you get a new Apple device , you can sign in with your Apple ID to store and access all your personal data in icloud , like your files , photos , contacts and calendars .
You can download previous purchases from the itunes store and App store and sign in to Apple Music .
If you ever lose a device , you can find it by signing in to the find my app .
Your Apple ID is also your account for iMessage and facetime with so many features and personal info tied to one account .
You can probably see why everyone should have their own Apple ID and avoid sharing it .
Say you let your child use your Apple ID on their iphone or ipad , they could accidentally delete your important notes or contacts and facetime calls for them would ring your phone too .
Instead everyone should have their own Apple ID to share itunes store and app store purchases and icloud storage with your family .
You can set up family sharing .
How do you keep your Apple ID ?
Secure first , use a strong password that you can remember .
Don't reuse it anywhere else and don't share it with anyone .
Then make sure you're using two factor authentication , which is designed to keep someone else from signing in as you .
Even if they know your password , when it comes to Apple , your Apple ID is the most important login you have .
So make sure the only one who can access it is you .
