I often don’t like single-anecdote stories, but occasionally they illuminate larger problems so perfectly they are worth telling. I’ve run into classic 21st Century Red Tape headaches with my bank recently as I try very hard to use its two-factor authentication scheme. Why? Because it doesn’t make me safer if it doesn’t work it just prevents me from accessing my money. This month brought yet another story chronicling theft of millions of passwords by hackers, once again highlighting the importance of implementing “not-just-passwords security” at places that really matter.īut I’m about to turn off two-factor authentication at my bank, right at the moment when everyone seems hell bent to turn it on. Both are equally important if a security scheme is to work. ![]() Security often fails because people who design security are much better at throwing up roadblocks than they are creating pathways. And that is the path to perdition (and hacking).
