TrustID Authenticator works with 2-factor authentication for your TrustID accounts. The app itself is protected by biometrics or PIN code. Sensitive data, such as the secrets of your second factors, are stored securely on your device only. When you access to a service using your TrustID account, a push notification will be delivered to your app that lets you confirm or cancel the sign-in process in an effortless way. If the notification service is unavailable, a traditional offline mode can also be used to not miss any sign-in sessions.

ASC C/D App Features: *The first page (Home Page) shows 3 liquid cartridges, used in the Automatic Shower Cleaner and even though it will not tell you an exact amount of the cleaning liquids in the containers, it will remind you to fill it up when it runs out of liquid. The message board is to guide you when you are setting up the unit very first time. *Next 4 pages are functioning as manual operators for up to 4 units. On each page there are Manual Start and Emergency Stop (E-Stop) Buttons. On each page there is a calendar function for scheduling the automatic shower cleaner, if you don’t want to start the process by pressing the Start Button. The message board, on each page is for guiding the user how to set up each unit, based on individual shower enclosure dimensions. On this page you can also adjust the Rotary Head rotation speed and liquid pressure, based on individual shower enclosure size. * Option page contains two functions. The first function is to allow the ASC C/D App users a quick access to instantly disable all 4 units’ automation schedule by selecting the days via slider, followed by pressing Disable Button, as a confirmation. The second function is to direct the ASC C/D App users to the webpage via www.ascmarket.com button, to obtain more information regarding the Automatic Shower Cleaner.
