About this app
The Postbank BestSign app is a separate app for securely authorizing orders in online banking. The app only includes the BestSign security procedure. Create and activate BestSign once, then you are ready for authorizing.
You can log into the BestSign app with your password or – if available – conveniently with your biometric data.
This app is useful if you do not want to use the Postbank app, as you mainly carry out your online banking on the computer and only need a security procedure for order authorization.
Tip: Try the Postbank app. Then you have your online banking and security procedures conveniently and securely in one place.

garbage, will rarely work on older phones. The app opens and closes by itself and the confirmation windows is gone. I have a samsung A14. You need a new phone with high ram for it to work reliably. Fix your application it shouldnt be this heavy and unreliable. Im a developer myself. I know what im talking about.

a bad one. every 5 min or so it is automatically turning out. a nightmare if one works with several transactions at once. therefore you have to go through the process of identification every 5 minutes. worst experience ever. the technical support is as always can't do anything, which adds to the frustration. One wonders if the one of the top banks in Germany can't get it right, what would you expect in other ones? compared to my Canadian experience, 2 out of 10 for Postbank.

log in often doesnt work due to 'technically difficulties' according to the error message, it rarely works on the first try despite the required info being correct sometimes on the 3rd try of enteting the same correct info you might be successful at logging in

Thanks for your feedback. The BestSign app is designed for users who use online banking via the browser of a second device. If you want to use online banking directly from your mobile device, we recommend our Postbank app. With the current app version, we offer an all-in-one solution with an integrated BestSign function.
