BiometricManager.Authenticators
| android.hardware.biometrics.BiometricManager.Authenticators |
Types of authenticators, defined at a level of granularity supported by
BiometricManager and BiometricPrompt.
Types may combined via bitwise OR into a single integer representing multiple
authenticators (e.g. DEVICE_CREDENTIAL | BIOMETRIC_WEAK).

Constants
BIOMETRIC_STRONG
public static final int BIOMETRIC_STRONG
Any biometric (e.g. fingerprint, iris, or face) on the device that meets or exceeds the requirements for Class 3 (formerly Strong), as defined by the Android CDD.
This corresponds to KeyProperties#AUTH_BIOMETRIC_STRONG during key generation.

Constant Value: 15 (0x0000000f)
BIOMETRIC_WEAK
public static final int BIOMETRIC_WEAK
Any biometric (e.g. fingerprint, iris, or face) on the device that meets or exceeds the requirements for Class 2 (formerly Weak), as defined by the Android CDD.
Note that this is a superset of BIOMETRIC_STRONG and is defined such that
BIOMETRIC_STRONG | BIOMETRIC_WEAK == BIOMETRIC_WEAK.
Constant Value: 255 (0x000000ff)
DEVICE_CREDENTIAL
public static final int DEVICE_CREDENTIAL
The non-biometric credential used to secure the device (i.e., PIN, pattern, or password).
This should typically only be used in combination with a biometric auth type, such as
BIOMETRIC_WEAK.
This corresponds to KeyProperties#AUTH_DEVICE_CREDENTIAL during key
generation.
