The company previously started offering some users a setting at the end of 2017 that allowed them to decide broadly whether face recognition was used in their Facebook experience or not. With the announcement on Tuesday, Facebook is expanding this option to all users.
Facebook said those who do not already have the feature will soon receive a notification in the news feeds about the change, along with an option to shut it off or turn it on.
Facebook relies on face recognition to send user notifications when their face is detected in a photo posted by a friend on the site – either person is tagged which can be helpful if someone is trying to use a photo of you as their profile picture. It also offered a feature called "tag suggestions" that used face recognition to automatically suggest users to tag specific friends in photos uploaded to the site. The company said that a visible setting for this feature would be discontinued.
