Facebook seems to be testing a new way for its users to authenticate their identity: Facial recognition. The feature was spotted in the wild and when asked to comment, Facebook promptly confirmed that it is testing it.
Facial recognition as a means of unlocking your social accounts hasn’t been done before. Facebook is changing it.
Facebook confirmed the existence of the test, explaining
We are testing a new feature for people who want to quickly and easily verify account ownership during the account recovery process.
They also explained that the feature is optional, and is “available only on devices you’ve already used to log in” as “another step, alongside two-factor authentication via SMS,” for rightful account owners can confirm their identities during account recovery.
