Facebook is testing the recognition capability of the person to restore access to your account. This was reported resource iDownloadBlog.
Face detection is an additional measure to protect your account, along with two-factor authorization. While the technology is being tested among a limited number of users. If it proves reliable, it can make public.
We are testing a new feature to enable users to quickly and easily confirm that the account belongs to them. This option is only available on devices that users already went into your account. Along with two-factor authentication via SMS, this feature will help confirm the identity.
Facebook constantly improves the security of your accounts. In addition to two-factor authentication through SMS messages, users can select from 3 to 5 friends with whom you can contact in case of problems with login.
