I do not use it on international travel
When traveling I don't think it's practical when you need the app and you don't have the AppleStore password. Outside your country you usually pretend that you didn't type the password correctly and you have all the hassle of checking the AppleStore password. If you do not remember the password then the inconvenience is done and you cannot access the bank. When traveling, I always take the Access Card, which is safer and can be accessed through the notebook. You don't get stuck. The App is well made and super practical in domestic use.
