Change who can see a post

You choose the audience for each post.

• Everyone: anyone can see it, and it may appear in recommendations.
• Friends only: only people you follow each other with.
• Only me: just you.

For a post you've already shared, use its "…" menu. Change the default for new posts in Settings → Create & camera → Default post audience. To limit your whole account to people you approve, make it private.
