buhl:Authenticator is a free Android app developed by Buhl Data Service GmbH. It is a Two-Factor Authentication (2FA) app that adds an extra layer of security to your customer account. Once activated, the app generates a security code that you need to enter along with your password to access your account, ensuring that only you can access your data, even if someone else knows your password.

Using the Time-Based One-Time Password (TOTP) protocol, buhl:Authenticator protects your buhl account and any other services, websites, or apps that support TOTP. The app is easy to use and generates the code automatically when you launch it. With this app, you can keep your data safe and secure from unauthorized access.
