Multi-factor Authentication enables applications to use more than one method of authentication to increase security. This is often summarised as something you have, something you own and something you are. MFA services can be delivered as a cloud or on-premises service that integrate with VPN, RDS and Citrix remote access solutions to name a few, through an identity provider such as Active Directory Domain Services or Azure Active Directory.
Username, password, PIN or security questions
Smartphone, one-time passcode or Smart Card
Biometrics, like your fingerprint, retina scans or voice recognition
With so many credentials having been compromised and made available to attackers, password-based security is no longer effective. Because Multi-Factor Authentication (MFA) requires multiple methods for identification, it’s one of the best ways to prevent unauthorized users from accessing corporate data.
