Hackers are learning to spy on you on YouTube I've heard that vulnerabilities in Facebook and other social media platforms are pretty common. I've heard less about such problems with Google products, but it looks like no one is immune.

There's always a way and something as simple as this might raise the bar and weed out the beginners, but it's not going to be anything that intermediate level hackers can't get around. Ultimately, it's almost certainly more hassle than it's worth. Most online accounts don't need anything more than a password and so this is the sort of thing I'd do only for online banking and other major financial transactions.
