What is Multifactor Authentication (MFA)?

October 14, 2023

Multifactor Authentication (MFA) is a safety precaution IT managers may take to require two or more user verification factors when accessing a network, an application, or specific data. Typical scenarios include combining something the user knows, such as a password, alongside something the user has like a token, a code, face recognition, or fingerprints. 

MFA is now acknowledged as a best practice in the IT world and is quickly being adopted by many companies to protect access to their network or core applications. It is commonly implemented by integrating an app such as Duo with Microsoft Azure Active Directory and can be managed centrally. 

Using the Duo/Microsoft Azure Active Directory combination, end-users log in with their password and are prompted via a phone app to approve or deny the request, or alternatively, to enter an authentication code. The process is easy and minimally disruptive, especially for users who connect remotely. 

MFA is also on the rise in the physical security world. For example, Salto’s electronic access control system can be programmed to require MFA for door access, and it is one of the easiest, most cost-effective ways to protect business structures.
