Twitch announced today that it is implementing optional two-factor authentication on its user profiles. The increased security measures, while "100 percent voluntary" according to the streaming site's release, are meant to improve user experiences while reducing the need for conventional, easily hackable passwords.Twitch is partnering with security firm Authy to run the authentication system. Unlike Google's two-factor setup, which relies on texts from your mobile carrier, Authy instead delivers push notifications through its app to confirm you are who you're logging in as. Users simply need to pair their Twitch and Authy accounts for it to work. Now we'll be able to enjoy Bob Ross Mondays without a care in the world.
