From the developer:
O2Face is a state-of-the-art desktop access control software based on our advanced facial recognition technology. It simplifies your Windows log on experience and frees you from creating and remembering complex passwords.
Since computers do not have a recognition function built in, users must input account information, passwords and other possible bits of information to manually log on to a traditional system.
