copy paste doesnt work.

Keyloggers tap into your system key typing function. Copy pasting doesn't work.
The best practise is to use authenticator to add 2 factor security.

If you feel like challenging yourself, install diablo on ubuntu, block all outgoing ports except 80 and 443, encrypt your pc and dns traffic, and play diablo

first install ubuntu on a vm image say ubuntu.
then install diablo 3 on ubuntu (linux os)
set up firewall that blocks all ports except for your d3 port(80) and ssl port (443).
If you want to one up that, set iptable to block all outgoing connection to IP other than battlenet using port 80 or 443,
use dns encryption to encrypt your traffic.

probably the most secure way to play diablo or wow.

they can if they either have your mobile authenticator info/config from either the server or the app.
the authenticator is just some numbers from your end which have to match the server side numbers, at a given time frame.

if someone got a dump of all the authenticator configs and details from server.
very possible to be gg

I would love to see the reaction if he/she decides to install on centOS or arch linux with minimal config.
