FaceIO, a facial recognition technology, has introduced passwordless authentication for websites and apps. With FaceIO, users can log in simply by looking at their webcam, eliminating the need for passwords or fingerprints. This innovative solution aims to enhance user experience and security.

To implement FaceIO on a website, developers must add the JavaScript library and create buttons for enrolling and authenticating users' faces. The process involves signing up for a FaceIO account, obtaining an API key, and integrating the technology into a website or app.

While FaceIO's passwordless authentication presents exciting possibilities, it also raises concerns about privacy and security. To mitigate these risks, developers must ensure that the technology is implemented responsibly, with proper error handling and user consent.
