new BiometricPrompt.PromptInfo.Builder()
                .setTitle("Login")
                .setSubtitle("Login to your account!")
                .setDescription("Place your finger on the device home button to verify your identity")

The BiometricPrompt class has the following callback methods:

new BiometricPrompt(activity, executor, new BiometricPrompt.AuthenticationCallback() {
            @Override
            public void onAuthenticationError(int errorCode, @NonNull CharSequence errString) {
                super.onAuthenticationError(errorCode, errString);
                // ................
            }

            @Override
            public void onAuthenticationSucceeded(@NonNull BiometricPrompt.AuthenticationResult result) {
                super.onAuthenticationSucceeded(result);
                // .............
            }

            @Override
            public void onAuthenticationFailed() {
                super.onAuthenticationFailed();
               // ................
            }
        });
