iCloud is already proving to be incredibly handy for syncing personal information, documents, and media across devices, but what if you’ve got someone—a spouse, roommate, or child, for example—with whom you’d like to be able to share some of your information? Luckily, there’s an easy way to do so. If the information you’re wanting to share includes Contacts, Calendars, Reminders—such as a shared shopping list—Bookmarks, or Notes, you can simply add your iCloud account as a secondary account on the other person’s device.
Simply open Settings, tap on Mail, Contacts, Calendars, and then tap on Add Account…. Choose iCloud from the list, enter your account information, and when prompted, turn on the options you want to share.
If you’d like to share Documents or have a joint Photo Stream with the person, you can do that too—simply setup the shared account as the main iCloud account on the both devices, then add personal accounts as secondary accounts using the steps above. Notably, this method will require you to share iCloud backups, but for families that need additional storage space anyway, this may save them from having to pay for additional storage for two separate accounts.
