kontonnz: the big question is why?
why would you want to automate something that has access to your bank accts; this just screams as a questionable thing to do;
the bnz uses two factor authentication any hows (not sure bout their business acts however??)
andrewinwlg: I assume that if someone is clever enough to figure out how to write the script to do the download (no easy task for ANZ as it always runs in a separate window), adding in encryption of the password in a file should be no biggie.
Doesn't matter if the banking opens in a new window, as long as the two factor authentication isn't one of those security passes, it wouldn't be that hard to duplicate a "legitimate" session, and download the data you require.
