BiometricManager.Authenticators
interface 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
const val BIOMETRIC_STRONG = 15: Int
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.
BIOMETRIC_WEAK
const val BIOMETRIC_WEAK = 255: Int
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.
DEVICE_CREDENTIAL
const val DEVICE_CREDENTIAL = 32768: Int
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.
