isSupported
Checks if biometric-only authentication is supported on the current device.
This method determines whether the device can support pure biometric authentication by checking for the availability of either weak or strong biometric authentication capabilities. It provides a permissive check that accepts any level of biometric authentication, allowing the authenticator to adapt between strong and weak biometric modes as needed.
Return
true if any level of biometric authentication is supported and available, false otherwise
Parameters
context
