So Apple introduced Family Sharing back in iOS 8, but I’m guessing most of you aren't utilising Family Sharing.
Family sharing allows you to:
Share location: family members can share their location.
iCloud storage: if you have a storage plan, then you can share it with your family.
Share purchases: You can share the media on iTunes, Book, and more app store purchased.
Screen time: if you have a child account in your family, then you can set screen limit and view reports.
Apple music: You can purchase the family plan subscription allowing you to share apple music with your whole family.
TV channels: If you have subscribed to a premium streaming service through the TV app, you can share it with your whole family at no added cost.
Apple Arcade: This is included with no added cost.
Apple News+: If you have the premium magazine and newspaper subscription in the News app, you can share it with your family at no extra cost.
Setting up on iPhone / iPad:
1. Go to "Settings" and tap on your "Apple ID" account at the top.
2. Tap "Set Up Family Sharing".
3. Tap "Get Started" and follow the on-screen instructions. You'll send a special iMessage to the people you want to invite. They'll need to tap on it to accept.
Setting up on Mac:
1. Open "System Preference"
2. Click "Family Sharing"
3. You'll be asked to confirm your Apple ID and then promoted for family members invite.
You are allows you add up to 5 family member but you can add and delete at any time.
