There were similar issues with Bunq in The Netherlands. You (or a scammer) could turn a savings account into a checking account pretty much immediately with one code, and then drain it in the matter of minutes. Lot of people lost their life savings over it and of course no one you could reach out to to rectify the situation. All other Dutch banks have waiting periods for this. E.g. ING has a four hour waiting period to increase your transaction limit, just so it buys time when potential scams are happening.<p>Of course it's easy to blame the user for this as they provide codes and stuff, but when one bank has this issue so much more than it should have given its amount of customers, something else is going on.
