We could use authentication to secure our accounts...

Would be nice. I feel like my account is very vulnerable compared to all my other game/email accounts that have one of those temporary password authenticators.

Yes, it's actually on its way. It has a support article for it, but I've lost it. I can get it for you later, but all it really says is that they're working on it.

Edit: here we go, it's not on the support site it's in the riotgames security page; http://www.riotgames.com/riot-games-security

it would be cool if they made authenticators (like there is for WoW/Final Fantasy 11 & 14) but having something like this would help especially for people who might not know their account is getting compromised!
