3 Risks and Downsides to Two-Factor Authentication. It's Monday morning. You are already stressed about starting a new week. So, in a piling on sense, I am writing again about two factor authentication, and its risks and weaknesses, just to mess with you. In all seriousness, you still need to use it; if only because it is the best security available right now. However, don't get complacent, and don't turn it off just because you find it inconvenient. Now, the risks. First, a hacker can still get into your accounts; or, at least, some of them, and, if he does, what if he resets two factor authentication to one of HIS devices? Oops. Now, you can't even get into your own account. Second, most sites have recovery systems that bypass the two factor system, in order to help you if you screw up or lose your second factor device. Authentication won't help you if a hacker can do that. Third, even if you have a strong password, they can be intercepted, or even given away in a weak moment. Read this article to know your risks, and be careful out there. Oh, and enjoy your Monday.
