Microsoft and Google are pushing for a password-less login system called FIDO 2.0 that uses unique private keys generated by scanning a user’s fingerprint or face for access. An Android phone’s fingerprint sensor could be used to approve a purchase on PayPal, for instance. Both Microsoft and Google have been pushing for FIDO 2.0's adoption. They're preparing to build the authentication technologies into their own internet browsers. On Monday, Microsoft said the next Windows 10 release would also support the standard too.
