Microsoft is considering a deployment of its biometric authentication system, Windows Hello, to smartphones and devices outside its immediate ecosystem.As was glimpsed on company slides at Ignite, the firm envisions a Hello deployment on “companion devices”.This could include wearables, as well as Apple or android smartphones.”When you think about a user and the kind of devices they carry with them,” Microsoft senior program manager lead Anoosh Saboori said during the session, “they normally have the phone in their pocket, they [might] have some kind of wearable on their arm, some of them might have the security fobs given to them by their company, and many of us carry a badge with us that is used to gain access to different physical locations. We wanted to leverage these devices as a way to knowing the user.”
