The verification app does tell you what the verification request is for. Also you can't really do anything in the bank without verifying yourself again (basically any change/write requires you to approve again)
Basically in the app you see if the verification is for logging in, providing strong auth for some service, approving transfer of X euros from Y account to account Z, etc
In general we have had really well working online banking since the late 90s here in Finland (first versions are actually from the early 80s where you dialed directly to the bank instead of your ISP with your modem). Haven't really heard of any major security flaws ever so they do have a really good track record. This is also why the governments attempt at creating their own strong auth service failed. The banks already effectively provide that and everyone is used to using them.
