Multi-factor Authentication (MFA) is an authentication method that strengthens access security by requiring 2 or more ways to verify user identity for gaining access to the PBX.
MFA works by requiring additional verification information (authentication factors) in addition to the username and password. These MFA factors are one-time passwords (OTP), which consist of 4-8 digit codes that the user receives via email, SMS or a mobile app. A new OTP code is generated each time an authentication request is submitted.
