Description

Returns what type of biometry is currently active (only in iOS).

Note: For Android it is not possible to determine what type of biometry is currently active, so GetBiometryKind will always return Unknown.

Possible return values are:

Unknown: Unable to determine availability - the method will always return this value on iOS
Available: Biometric authorization is available
HardwareUnavailable: The hardware for biometric authorization is unavailable
NoHardware: The hardware for biometric authorization does not exist
NoneEnrolled: No Face ID and/or fingerprints are enrolled for the current user
SecurityUpdateRequired: Biometric authorization needs a security update before it will be available
Unsupported: Biometric authorization is not supported on the device
