Hopefully by now you’ve heeded the repeated warnings from your friends and loved ones (and friendly, beloved internet writers) to use two-factor authentication to secure your digital accounts. That’s where access to Facebook or Twitter or your online bank—anything that supports it, really—requires not just a password but also a special code. Not all two-factor is created equal, however. For better protection, you’re going to want an authenticator app.
Yes, the easiest way to implement two-factor is with SMS, receiving a text with an access code every time you try to log into a secured account. While certainly better than nothing, getting your 2FA from SMS has plenty of potential downside. Specifically, it leaves you exposed if someone hijacks your smartphone’s SIM, a longtime problem that has only gotten worse of late. By stealing your phone number, hackers can redirect any two-factor notifications to their own devices, allowing them much easier entry to your accounts.
