I am using deviceOwnerAuthentication policy of local authentication for biometric authentication. If user have not added any fingerprints or faceID, is there a method to determine it. LABiometricType is only checking if the device can support the touch/face ID. Couldn't find a method to determine if the user have added it.
To determine If user have not added any fingerprints or faceID using Local authentication.
If the user hasn't enrolled their face or fingerprints, or biometric authentication on their device is broken, or they've turned it off, then you will be told that authentication isn't available - and that's exactly what you want. You shouldn't need to be told that they've not added any fingerprints; you just need to know whether or not they can authenticate with it. Leave the minute of its setup to the user and the operating system.
