I don’t think it’s going to get much more broadly used than it is now. I work in cyber security and there have been password hacks like this since practically the beginning of the internet. It’s called a rainbow table attack, It mostly relies on the victims being complete idiots.

You don’t even need to have a particularly secure password to be safe from it, you just have to have a unique one from site to site. Even if in other respects it’s relatively weak it will still defeat a rainbow table attack.

The point is this stuff has been going on for decades and people are still making basic fundamental errors, so I can’t see how that’s going to change in the future. Maybe we should require everyone to take some sort of basic proficiency test before they’re allowed online.
