Wow that's crazy talk. Waiting an extra 2 mins to get all 5 accts logged in is of minor consequence.

If you got hacked, you would have to wait the whole day while they locked down your acct. You prove who you are. They then reactivate your accts. Then it could take up to 3-4 days to get all your gear back if it was sold off or destroyed. You may or may not get any items or gold from the hacker's colleagues. That's not a given at all. I would say that's a bigger inconvenience then 2 extra minutes for the security of an authenticator.

Trust me I have friends who have been hacked and it's no laughing matter. Especially when they have to sit all weekend waiting for their accts to be restored. I can't vouche for how they got hacked in the first place but regardless getting hacked sucks.
