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.DATA PRIVACYProtecting your data is our highest priority.
