The question is not whether you should have multifactor authentication (MFA); instead, what type? MFA is utterly essential when it comes to your business and personal data security. In the world of multifactor authentication, not all avenues are created equal. Although having something is better than nothing, in this case, that is not the attitude that you should have concerning your security. In 2016, NIST (National Institute of Standards and Technology) proposed restricting the use of SMS or voice for MFA, and although they softened their approach, they still do not recommend this method of MFA. Microsoft recently began campaigning against using SMS or voice for MFA. Today we are going to look at why the big push and what avenue is best for MFA.
