The idea of using facial recognition as an authentication mechanism was around for decades, largely popularized by science fiction. Thanks to the huge leap in Machine Learning advance in the last few years, such technology, proved to be plausible to implement.
Facial recognition, as a contactless, passwordless method of authentication, proven to be superior to standard password based logins, multi factor traditional authentication (MFA), one-time codes (OTF), authentication scheme. In order to strike the perfect balance between security, privacy and user experience, the underlying technology must address a few key issues: vulnerability to spoofing attacks, recognition speed & efficiency, but most importantly, privacy and civil liberty concerns.
