This is why Facebook is giving you another option – Face ID Authentication. According to Facebook, the facial recognition feature for verifying an account will be only available on those devices that users have already used to log in. Currently, it is testing it by making the feature available to a small number of users. If the feature proves to be reliable and cannot be fooled by hackers, it may be made available to wider audience.
Here is a screenshot of the new facial scanning feature shared by Matt Navarra
How Will The Facial ID Work on Facebook?
You will be required to hold their phone to their face and then the Facebook app will scan the face and compare it with the tagged images and videos of the user that are present on the site. Once a match is found, the account will be unlocked.
As pointed out above, if the facial scanning feature is highly reliable and cannot be hacked by using a picture of any user, Facebook may consider rolling it out to mass audience.
