Certain options are only adjustable on your device, like iCloud Storage and Family Sharing settings. While changes to your Apple ID are not on iCloud.com or your device, but rather appleid.apple.com. This guide will help demystify and inform you about the most important settings for your iCloud account: security.

This is a nice walkthrough to both reset and learn about your iCloud security settings.

Personally I think the best step is to use a dedicated and unique email address for iCloud. That way, no one can figure out your login from an email or some other login.
