Facebook Privacy Lockdown in 10 Minutes

Who sees your posts, who finds your profile, and which apps siphon your data — the settings that matter.

  1. 1. Run Privacy Checkup first

    Settings → Privacy Checkup walks through who sees posts, profile info, and friend list. Set past posts to Friends in one tap and limit profile discovery to friends-of-friends maximum.

  2. 2. Revoke third-party app access

    Settings → Apps and Websites → remove everything you don't actively use. Quizzes and ancient games hold tokens that survive password changes — this is where most 'how did they post as me' stories start.

  3. 3. Lock login alerts and 2FA on

    Security → Two-factor authentication (authenticator app, not SMS) plus alerts for unrecognized logins. Review active sessions and kick anything unfamiliar — then keep it that way.
