Traditional passwords aren’t secure enough anymore. From simple relaying and spraying attacks to the more sophisticated threats of spear-phishing and pharming, hackers have developed countless tried and tested methods of stealing credentials and gaining unauthorized access to private accounts. In March this year, Microsoft engineers said that 99.9% of the account compromise incidents they deal with could have been blocked by a multi-factor authentication (MFA) solution.
Multi-factor authentication is an electronic authentication method that requires the user to provide two or more forms of identity verification before they’re allowed access to a website, network, or application.
There are three main types of MFA. The first is something you know. This includes passwords, PINs, and even secret knocks. The second type is something you have. This is a physical object, such as a key or smart card. The third type is something you are: biometric verification. This could be a fingerprint, retina scan, or voice recognition.
Two-factor authentication (2FA) uses two of these possible checks to verify and authorize a user’s access attempt, whereas multi-factor authentication uses two or more of these checks. This makes MFA a stronger solution than 2FA, though just as easy to implement.
Multi-factor authentication solutions are relatively inexpensive and often extremely easy to deploy. They provide simple but effective protection to individual users and the wider business network. So instead of asking yourself why you need to enable MFA, it’s time to ask yourself why you haven’t already done it.
