Welcome to Microsoft Q&A!
From Android 10 (API level 29) we can use AndroidX Biometric Library to authenticate , the library does not expose a separate API for Facial Authentication because it is not responsible for targeting specific form-factors . If a device supports facial biometrics, then you will see a prompt for facial authentication; if your device supports fingerprint biometrics, then you will see a prompt for fingerprint authentication; and so on.
