Santosh - how valuable it might be, I am unable to understand how this is relevant to Wikimedia projects. Maybe you could elaborate on anything that is not obvious. Also, face recognition leads to the questions related to questions on privacy, personal data collection, and even surveillance. For instance, there is a huge debate going on about the potential issues related to the face recognition based security gates that have recently been installed in several Indian airports. Face recognition for logging into Wikimedia projects might just open a pandora's box as the anonymity of contributors is core to Wikimedia projects. I am not sure if there is any discussion that exists anywhere about even adding a test project but I'd highly discourage biometric-based authentication. I think this community and probably the foundation does not have the legal, technical and other infrastructure that is required to manage a few hundred thousand personal data including biometric data as the latter is extremely vulnerable. Any data breach could cost lives. Many of our community members work in regions with geopolitical conflicts and biometric data tied to one's Wikimedia contribution could potentially lead to danger to their lives. Similarly, there is not enough education about individual privacy and biometric data collection which is why many online users, out of ignorance, end up sharing their private details online. The more the personal data collection options on a platform, the more the risk of that data being leaked and misutilised. No offense to the hard work, but {{STRONGLY DISAGREE}} for any such projects even on an experimental basis.
