This is terrifying to me, and part of the reason I've kept the little authentication calculator instead of moving to the app. Also the app won't work on root and has a fairly narrow range of Android versions it's compatible with.

I travel a lot and I would benefit from opening a "global money" account. However this requires the app, so I've never done it.

If they ever drop support for the physical authentication calculator, I will move to a different bank that doesn't require an app. Which is increasingly difficult these days.
