How does the authentication work for Trade Republic?

- Every time you switch between Outbank and the Trade Republic App, you need a TAN.
- Every time you make a fetch in Outbank, you will be notified via mail from Trade Republic, about the registration of a new device.

This is not a bug, but part of the strong customer authentication at Trade Republic.
