Biometrics are everywhere. Almost all smartphones these days, even mid-range ones, have fingerprint scanners. Laptops and convertible tablets are slowly getting there. And while Apple seems to be doing away with them, it is replacing fingerprints with faces, yet another biometric security factor. The only place where this secure authentication method isn’t available is where they matter the most: the Web. But if the World Wide Web Consortium, a.k.a. W3C, has its way, even websites like, well, Facebook will support password-less logins in the near future.
