How to make your Facebook as private as possible: Adjust your profile's privacy settings

• You can use Facebook's Privacy menu to limit who can see your posts, profile, and more.
• Setting every option to "Only Me" will make your Facebook profile completely private.
• You can also set up reminders to update your privacy settings using the Privacy Checkup tool.
