TouchID (e.g. SecItemCopyMatching) determine which fingerprint was used

Is there any way to determine which fingerprint was used to unlock the key chain data? E.g. if we have two customers then we might store a separate username/password with each fingerprint.

Is this for Android? Please update your tags with the OS.

For Android and a GMS certified device, I don't think you will be able to access fingerprint-specific info on Android 6.0+.

See: https://source.android.com/compatibility/7.1/android-7.1-cdd.pdf

Section: 7.3.10, 10th bullet

  • MUST NOT enable 3rd-party applications to distinguish between individual fingerprints.
