What this authorization app is for

Secure TAN is the approval app for finanzen.net zero brokerage accounts. It is not the trading app, which the developer lists as a separate download called finanzen.net zero Aktien & ETF. This one only confirms operations: transactions, bank transfers and other account actions that the depot requires to be approved on a registered device.

It suits people who already hold or are opening a finanzen.net zero depot and want their approvals handled on a phone. The listing describes it as free.

Linking a phone to a finanzen.net zero depot

Setup starts on the web. You open a depot at finanzen.net/zero if you do not have one, then register your phone or several devices online. Once the depot is fully opened, you go to Verwaltung, then Sicherheit, and add the device there. The depot then issues an activation code.

On the phone you scan that code in the app, which unlocks the device for approvals. The listing presents this as a five-step sequence, and the steps must be completed in that order before the app can approve anything.

Approving transactions and transfers by push

After a device is linked, you no longer copy codes by hand. When a session needs releasing, the app sends a push notification and opens the approval request inside the app. You confirm it there.

The listing says this covers transactions, transfers and other operations, so one app handles every approval the depot asks for, not only logins.

Using several devices and keeping the trading app separate

You can register more than one device to the same depot, and each one is added and activated the same way. The listing does not describe how approvals are split between devices.

The trading app and this authorization app are two downloads with two jobs. The developer's own guide suggests installing the trading app only when you need it, while Secure TAN stays on the phone that receives your approval requests.
