Biometric Unlock
Using a local biometric match such as fingerprint or face recognition to unlock a device or authorize use of a protected credential.
The useful mental model.
Start with the part that changes what you actually do or expect when you meet this concept in everyday digital life.
What is actually connected
Trace the path between device, account, network, cloud service and other devices. “Smart” often means those layers are cooperating.
Where dependence appears
Convenience can depend on a working account, compatible ecosystem, subscription, network or remote service. Knowing the dependency makes failures easier to understand.
What connects to this?
Digital life is a system. Follow the neighboring identity, data, design, security or business layer instead of stopping at one definition.
