We talk about passwords a lot. Create strong passwords. Use upper- and lower-case letters, numbers, and symbols. Use a password manager. But the easiest way to unsecure your password is to share it. Realize that if you share your password with someone else (family member, coworker, etc.) they have access to EVERYTHING in that account. If a department needs shared information, create a SharePoint site. Use Google Drive or another similar sharing app if your family needs shared information. There are many ways to share information that is much more secure than password-sharing.
