Enabling this will allow scheduling of payment.
When the name similarity between contact name and network name fails, the payments to the contact are blocked.
Enabling this will require two factor authentication for all users.
If this is on, payments will be queued and retried when funds are low. Otherwise, they
will be rejected immediately. If you submit payments via the API, turning this off will result in faster responses to your requests.
Enabling this will reject any collection that was not requested by you, or whose request has expired.
