One of the primary vehicles used by bad guys to access our systems is stealing log-in credentials in order to impersonate real users. All the security processes and tools in the world are circumvented when someone has your username and password.

That’s where two-factor authentication (2FA) comes into play. 2FA works by adding another authentication challenge to the equation. It’s not just about what you know – your password, it’s also about something you have. That’s where the authenticator apps from Microsoft and Google come into play.
