Due to changes in the Payment Services Act, the Mobile key will replace the paper key code list this summer for all OP-mobile users. For Android users, the change will take place in June, while iOS users will move to using the Mobile key by the end of the summer.
After the change, you can no longer use OP-mobile without the Mobile key. However, you should still hold on to your key code list. You’ll need it when using the op.fi service or third-party services, such as MyTax or Kela, or for shopping online. You’ll also need it when you want to enable OP-mobile or OP Business mobile on other devices.
