Julliet&Koen Both of you need to register. It's not allowed to get a single Premium subscription and both log in with the same username/code. You both need to verify your identity etc. Now, when you've done that you can set up the shared account. You then create an IBAN that is visible/usable by both users. For this one of you can have a Free account, as long as the initiator has Premium. The downside is that the free account does not include any cards, so the free account won't be able to get either physical or online cards. For that you both need a Premium subscription. I hope this clarifies the matter. 🙂
