Access a Mobile Device’s Biometrics Capabilities
A Lightning web component can use a device’s biometrics functionality to prompt a user
to confirm their identity. When these biometrics-related actions occur, the result is returned
to the Lightning web component that invoked it.
Biometrics checks are managed locally on the mobile device, and don't need a network connection. However, BiometricsService requires access to platform-specific APIs that are available only within compatible Salesforce mobile apps.
