BIOCAT - the easy way to configure your BIOCAT KLS device. The BIOCAT app allows mobile configuration of BIOCAT KLS devices via Bluetooth or the Internet. Registered users receive advanced operating functions, such as adjusting settings, as well as push notifications in case of leakage alarm directly to their smartphone. Detailed assistance in case of leakage alarms as well as a (manual or automatic) leakage check of the piping allows the user to identify potential sources of danger in the water pipes at an early stage and to minimize damage. In addition, the user gains insight into his water consumption data as well as statistics on the course of consumption behavior.
LE Authenticator

The LE Authenticator secures your accounts with a two-factor authentication. For this purpose, the LE Authenticator generates one-time codes that have to be used together with your normal password. This makes it almost impossible for unauthorized users to log in. The LE Authenticator is compatible with the TOTP and HOTP standards and can therefore be used for most websites and providers with two-factor authentication. Simply scan the required data with the built-in QR code scanner or enter the data manually. Assign your own images or icons of the providers to your entries in the app so that you can keep a better overview. If you have a large number of different tokens, you can use the search function to log in as quickly as possible. For even higher security, you can additionally secure the app with a PIN code and Face ID or Touch ID. All stored data is securely encrypted by the operating system. Particularly sensitive data is stored in the device's keychain. The app does not require an Internet connection; all data remains locally on the device. We are very happy about your feedback and suggestions for improvement.
