Enable two-factor authentication for SSH in Linux

Par : Surender Kumar

In this article, you will learn how to enable two-factor authentication for SSH in Linux. Secure Shell (or SSH) is primarily used by admins to securely access and manage remote computers, particularly those running Linux. It supports two very common forms of authentication: password authentication and public key authentication.
