Users with administrator rights can remove bank connections from the overview. To avoid accidental deletion, this page is shown to confirm the operation. It also shows, which data would also be deleted, such as open payments, fetched and sent files, as well as account statements.
If there is only one bank access left in the list of bank connections, this cannot be removed.
Please consider that no corresponding order is sent to the bank during deleting a bank access. That means the state of the user on the bank side is not changed. If you want to make sure that the bank access cannot be used any longer, you should lock the bank access before deleting. This process is described in section Lock bank access.
