What’s going on with SMS Authentication? How come it’s still a thing!? In fact, SMS is still the most commonly used form of Multi-Factor Authentication (MFA) on the planet.
If you doubt this, think globally. Don’t be limited by your own experience, even though I bet you still receive more OTPs (One-Time Passwords) by SMS than you care to think of, no matter how many smartphone apps and google auth accounts you have!
