The nullok option allows a user who has not set up two-factor authentication to log on using a username and password. After 2FA configuration and testing, it is recommended to disable the option to require using two-factor authentication. Then edit /etc/ssh/sshd_config: sudo mcedit /etc/ssh/sshd_config
Two-Factor Authentication ( 2FA ) using OpenOTP. This guide is for security-aware individuals who wish to learn the theory behind user- based two-factor (or multifactor) authentication systems, also known as 2FA . Here we will discuss how 2FA systems work, and how to implement 2FA into a small, virtualized environment for testing purposes.
