Two factor authentication are a vital element of a secure security infrastructure. They reduce the risk of insider threats or accidental data breaches, and also ensure compliance with regulatory requirements.
Two factor authentication (2FA) is a process which requires the user to enter a credential in two categories in order to log into an account. This could be something that the user is familiar with (passwords PIN codes, passwords security questions) or something they have (one-time verification code that is sent to their mobile, or an authenticator application) or something they ARE (fingerprints, face, or retinal scan).
Most often, 2FA is a subset of Multi-Factor Authentication (MFA) that has more than two. MFA is typically a requirement in certain industries, for example healthcare (because of strict HIPAA regulations) as well as e-commerce and banking. The COVID-19 pandemic has also increased the importance of security for companies that require two-factor authentication.
Enterprises are living entities and their security infrastructures are always changing. Users shift roles, hardware capabilities are evolving and complex systems are accessible to users. It is essential to periodically review your two-factor authentication plan at scheduled intervals to ensure it is able to keep up with these changes. One way to do that is through adaptive authentication which is a kind of contextual authentication that sets policies based upon how the login request is received. Duo provides a central administrator dashboard that allows you to easily set and monitor the policies of these kinds.
