Multi-factor authentication serves a vital function within any organization – securing access to corporate networks, protecting the identities of users, and ensuring that a user is who he claims to be.

Yet the recent surge in high-profile security breaches, as well as evolving business environments that require entirely new considerations for access control – like SaaS applications and mobile device management – represents a shift in how trust and control is established and maintained.

Multi-factor authentication (also Two-factor authentication, TFA, T-FA or 2FA) is an approach to authentication which requires the presentation of two or more of the three authentication factors: acknowledge factor (“something the user knows”), a possession factor (“something the user has”), and an inherence factor (“something the user is”).
