Introduction<\/h2>\n

SSH (Secure Shell) keys provide a more secure way of logging into a server with SSH than using a password alone. In this guide, we’ll walk through the steps to generate SSH keys on Ubuntu 20.04 and configure them for use.<\/p>\n

Prerequisites<\/h2>\n

Before proceeding, ensure you have:<\/p>\n

    \n
  1. An Ubuntu 20.04 server<\/li>\n
  2. A local computer with SSH client installed<\/li>\n<\/ol>\n

    Steps to Set Up SSH Keys<\/h2>\n
      \n
        \n
      1. Generate SSH Key Pair:<\/strong> Open a terminal on your local computer and run the following command to generate an SSH key pair:<\/li>\n<\/ol>\n<\/ol>\n
        ssh-keygen -t rsa -b 4096 -C \"your_email@example.com\"<\/code><\/pre>\n
          \n
            \n
          1. Copy Public Key to Server:<\/strong> Use the following command to copy the public key to your Ubuntu 20.04 server:<\/li>\n<\/ol>\n<\/ol>\n
            ssh-copy-id username@hostname<\/code><\/pre>\n
              \n
                \n
              1. Configure SSH:<\/strong> Edit the SSH configuration file on your Ubuntu 20.04 server to disable password authentication and enable public key authentication:<\/li>\n<\/ol>\n<\/ol>\n
                sudo nano \/etc\/ssh\/sshd_config<\/code><\/pre>\n
                Add or modify the following lines:<\/p>\n
                PubkeyAuthentication yes\r\nPasswordAuthentication no<\/code><\/pre>\n
                  \n
                    \n
                  1. Reload SSH Service:<\/strong> Reload the SSH service to apply the changes:<\/li>\n<\/ol>\n<\/ol>\n
                    sudo systemctl reload sshd<\/code><\/pre>\n
                    Conclusion<\/h2>\n
                    Congratulations! You have successfully set up SSH keys on your Ubuntu 20.04 server and configured them for use. SSH keys provide a more secure way to authenticate with your server compared to password-based authentication.<\/p>\n
