Top Six Hurdles in Implementing Phone-based MFA



MFA is an authentication technique that is used as an additional layer of security for enhanced user account protection. It goes beyond the first-degree of authentication – typically a username and password – that most consumer-driven businesses have.


Depending on the industry and the applicable regulatory or compliance needs, MFA can be used in several variants such as:
