2FA or two factor authentication provides a second layer of security when accessing all different types of applications in different environments. The types of environments which can use two factor authentication include web based applications, cloud computing, SaaS environments, corporate extranets, and virtual private networks. When users attempt to access these types of environments, they are challenged for a second type of authentication.
Users Are Not Granted Access When They Have the Wrong 2FA
What happens when a user does not have the correct 2FA available? They are not granted access to the type of environment they were attempting to log into. Even if they know their user name and password, they can try all day without any success if they don’t have the correct two factor authentication key. Two factor authentication can use different configurations, depending on your computing environment. You can use configurations including digital certificates, USB tokens or smart card tokens.
