I have used keyguard manager unlock page to open my application. Currently, I have used following implicit intent to launch android unlock page.
KeyguardManager km = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
Intent i = km.createConfirmDeviceCredentialIntent("title", "description");
startActivityForResult(i, requestCode);
In unlock page it is showing only following two options
Pattern/Pin
Fingerprint
How to add face unlock too?
