It will roll out the Face Recognition privacy setting globally over the next several weeks.
Facebook is making facial recognition in photos opt-in by default. Starting today, it’s rolling out its Face Recognition privacy setting, which it first introduced in December 2017, to all users. If you have Face Recognition turned on, Facebook will notify you if someone uploads a photo of you, even if you aren’t tagged. You can then tag yourself, stay untagged, or report the photo if it’s something you want taken down.
