Regardless of the fact that the master password can be brute forced on a machine running a couple of powerful graphics cards, it's refreshing to see 1Password address the situation so openly without making excuses or denying anything. They've always had great customer support and I have no doubt they'll make this a priority to fix as they've so openly said. This doesn't make me feel any less safe, while the chance is there that an attacker could brute force my data, I find it highly unlikely it'll happen between now and when they implement the new cipher. Bravo to Atom for discovering this and coming up with an exploit that can guess 3 million times per second using a graphics card processing unit.
