Yes, there is. As an alternative to confirmation with smsTAN, you can also pair your smartphone with your Penta business account. This is especially useful if you have poor network reception or are abroad.
- download the Penta App (iOS | Android)
- go to the app settings and click on "device tethering"
- follow the instructions and pair your smartphone
Done! You can now log in to your Penta business account without entering an smsTAN.
