How do I change saved credentials and/or TAN method?

Licensed mandators or Web Form V1 mandators

Bank connection settings, like stored credentials and/or default TAN method, can be removed/modified using the “Edit a bank connection” service.

Web Form V2 mandators

To change the bank credentials or the standard TAN method saved with us, you can use the 'Update a bank connection” service ("POST /api/tasks/backgroundUpdate").

In the request body, you have to set manageSavedSettings to either CREDENTIALS or DEFAULT_TWO_STEP_PROCEDURE, depending on what setting you would like the user to update. The generated web form will prompt the end-user to change their credentials/TAN method accordingly.
