Two things with respect to the authenticators:(1) I have been using a similar device (from another company) for my on-line banking for almost six years now and the battery is still going strong. So this is not much of a worry.(2) Also, not only are the generated codes limited by time, they are consumed upon use too. You cannot use the same code twice (just checked this - generated a code, logged in to my bank, than logged out and tried to log in immediately with the same code - did not work) - so unless someone can snatch the code from you AS you are entering it and log in faster then you, it seems to be quite safe.

Thats not true with the Blizzard authenticator. I have a couple of accounts and can use the same code to log into each (assuming I'm logging them both in at the same time). It might make a nice upgrade to their software though.

Likely that you can use it on multiple accounts in the time-window, but only once on a single account.Just tested. Logged in with one code immediately after it refreshed, got to character pane and cancelled back to login. Tried logging in again with the same code, reported "Information not valid".
