Tech companies have been trying to do away with web passwords for years, but now it looks like they've reached a key milestone. The FIDO Alliance and W3C have launched a Web Authentication standard that makes it easier to offer truly unique encryption credentials for each site. That, in turn, lets you access virtually any online service in a PC browser through password-free FIDO Authentication, not just specific services. You can continue to use familiar methods like fingerprint readers, cameras and USB keys, and it can serve both in place of and in addition to passwords.
