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. Microsoft engineers said that 99.9% of the account compromise incidents they deal with could have been blocked by 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 being allowed access to a website, network, or application.
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.
