Why You Must Use 2FA/MFA!

Two-factor authentication (2FA) or multi-factor authentication (MFA) is critical for securing your cloud-based or remotely accessible systems by adding a second verification step (two-step) in the logon/authentication process.

The security of two-step verification lies in its layered approach. Compromising multiple authentication factors presents a significant challenge for attackers. Even if an attacker manages to learn your password, it is useless without also having possession of the additional authentication method. It works by requiring two or more of the following authentication methods:

  • Something you know (typically a password)
  • Something you have (a trusted device that is not easily duplicated, like a phone)
  • Something you are (biometrics like fingerprints or facial recognition

Typically it works like this:
