PSD2: Changes - two-factor authentication on login
In order to login to your online banking, the PSD2 requires not only your PIN and account data but also a transaction number (TAN), which you generate with the mobile TAN, to be used for the login.
You log in as usual with your user ID and password. Please note the information on the following page. Before you gain access to your online banking, it is necessary to confirm again via mobile TAN. Once you have entered the TAN sent to your mobile phone number stored with us, you can use Online Banking as usual.
