Multi-Factor Authentication
for Linux Login

Linux Multi-factor authentication (MFA) is a type of authentication that requires a user to provide two or more (multiple) verification factors in order to gain access to data/resources/system,etc. In an Identity and access management (IAM) policy, this type of MFA/2FA security measure is more effective than a single password and is a must have for all organization looking to increase the security for their sensitive data and information.

With Multi-factor authentication (MFA) or Two-Factor Authentication, an unauthorized person is more likely to have difficulty accessing a target, such as a location, a computing device, a network, or a database. Utilizing MFA/2FA aims to increase security and provide a layered defense so that, even if one factor (username-password) is stolen or a targeted cyber attacker manages to get past one barrier, they still have at least one more to overcome before successfully accessing the real targeted device. When opposed to ordinary username passwords, the second barrier is typically more difficult to get past.
