Multi Factor Authentication

Multi-factor Authentication (MFA) is an authentication method which is used to ensure that digital users are who they say they are proving two or more verification factors to gain access to a resource such as an application, online account, or a VPN. MFA requires one or more additional verification factors, which decreases the likelihood of a successful cyber-attack. If one of the factors has been compromised by a hacker or unauthorized user, the chances of another factor also being compromised are low, so requiring multiple authentication factors provides a higher level of assurance about the user’s identity. One of the most common MFA factors that users encounter are one-time passwords (OTP). OTPs are those 4-8-digit codes that you often receive via email or SMS. With OTPs a new code is generated periodically or each time an authentication request is submitted.
