We checked the TAN query at N26. Unfortunately, there is no way on our part to influence the frequency of the query.
As a workaround, you can e.g. from the automatic update. It will then no longer be updated automatically when the app is started and in the background and you will have to query/confirm less often.
You can of course still update the account manually at any time: ‘Open account settings’> activate the switch at ‘Exclude from broadcasting’.
If you combine all accounts of an account in an account group and update this group, only a single confirmation / TAN query is necessary for the entire group.
