Reminder Sharing
This is different from multi-user reminder access. With multi-user reminder access, you can add users to a single reminder on a single account and let other people use that single account.
But with reminder sharing, you can simply send a reminder like sending a text to your friends and loved ones. Reminder sharing will allow that reminder to be set on their My Reminders account. Reminder sharing will help you create reminders for someone who might not be able to set the reminder themselves because of various reasons. Both multi-user reminder access, as well as remainder sharing, will make it easier for you to set reminders for your loved ones.
