Microsoft thinks it's high time you ditch your passwords. The company, which is readying Windows 10 for a late 2015 release, just announced that its next-gen OS will include built-in support for several alternative log-in options, including fingerprint, facial and iris recognition. That means so long as a Win 10 machine has at least one of the necessary sensors -- a fingerprint reader, eye scanner or illuminated IR sensor for facial recognition -- there will be a built-in framework called "Hello" that helps users enroll their fingerprints, or face, or what have you. In other words, then, regardless of who made your machine (Acer, HP, et cetera), you'll get a consistent user experience for setting up a biometric log-in.
