Consorsbank is currently requesting strong authentication (TAN input) for every request sent to the bank. This happens before the bank can be told whether the balance should be queried or a transfer made.
For this reason, you have to enter 1 TAN for the account inquiry and 3 TANs for transfers.
An automatic recognition of the TAN from the SecurePlus app is currently not possible. The bank does not offer this interface for third party providers.
You will find detailed information about PSD2 in our blogpost.
