This article explains how to prevent strangers from seeing your Facebook profile by limiting your future posts and changing the audience for posts you've shared in the past. It also includes information on how to see everything you're tagged in and how to limit who can send you friend requests or look you up.

Select the down arrow in the top right corner of your Facebook home page.
