Control Your Privacy on Facebook
Click Who Sees Tag Suggestions . . . ?
Facebook can recognize your face in other people's photos and recommend your name as a tag when they're uploaded. The only options for this feature are Friends and No One. If you turned on Timeline Review in Step 6, you would have to approve tags anyway, so leaving this Enabled is simply a timesaver for your friends — and a boon to you if you have a name that's difficult for your friends to spell.
Facebook will not recommend your name as a tag in photos uploaded by people you haven't friended. And those tags are just recommendations, too; your friends might not even use them, and you won't automatically be linked to pictures of people who look like you but aren't (an encouraging thought for identical twins).
