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. It is always recommended to use public key authentication for SSH access since it is more secure. However, if you still depend on password authentication, it is highly recommended to enable two-factor authentication.
