key authentication

Secure Shell (SSH) is a protocol used by countless tech professionals worldwide to manage systems remotely, enabling them to execute commands, tweak settings, and handle files from any location. As fundamental as SSH is, securing SSH access is just as crucial. One of the most robust methods to secure SSH is through key-based authentication, an alternative to the traditional username and password combination. However, setting up SSH key authentication can vary slightly across different Linux distributions. Today, we'll delve into these variations, focusing primarily on popular distributions such as Ubuntu, Fedora, and CentOS.
