Multi-Factor Authentication


Multi-Factor Authentication should be a core component of IT security for businesses of all sizes.


With Calligo and Duo, deploy it in minutes to every user.

What is Multi-Factor Authentication?


Multi-factor authentication (MFA) is a network security process that requires users to input more than one method of authentication.


These are typically a combination of:

  • What the user knows e.g. passwords
  • What the user has e.g. a second device
  • What the user is e.g. biometrics

Most Multi-Factor Authentication strategies start with a password, and then have additional measures on top, usually a one-time code from a second device, a push request through a second application, a fingerprint ID, or a geo-location verification.


Why deploy Multi-Factor Authentication?


Passwords are almost certain to be compromised at some point through social engineering, phishing or keylogging, so by adding additional layers, or "factors", to the network defence, it becomes far harder for unauthorized individuals to access your data.


Calligo believes that Multi-Factor Authentication should be the default position for every company.

So much so that we strongly recommend it for every IT Managed Services customer.
