Simply open the KodyPay app and tap on your profile, which is on the top left of the home screen. Once on this page, head to the top right, where you can open your settings. Then, tap the "Login with biometrics" switch. Once the switch slides over, you'll get a brief prompt on your device to ensure it's you. You have now enabled biometrics to verify it's you every time you open the KodyPay app.
