8.3.3 Turn On Extra Sign-In Protection
Open Security from your profile menu. Turn on the available two-step sign-in option approved by your organization. If cashier PIN, device trust, or connected sign-in accounts are shown, review them and remove anything no longer needed. Save the change and test sign-in before closing the setup.
PLATFORM WARNING: Do not create production keys or webhook subscriptions from a personal account that will not remain with the support team. Use a named business owner and documented fallback contact for every live integration.
