You can specify a different location, and an optional password ( passphrase) to access the private key file. By default, these files are created in the ~/.ssh directory.
Use the ssh-keygen command to generate SSH public and private key files. VMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.įor more background and examples, see Detailed steps to create SSH key pairs.įor additional ways to generate and use SSH keys on a Windows computer, see How to use SSH keys with Windows on Azure. You can complete these steps with the Azure Cloud Shell, a macOS, or a Linux host.įor help with troubleshooting issues with SSH, see Troubleshoot SSH connections to an Azure Linux VM that fails, errors out, or is refused. This article shows you how to quickly generate and use an SSH public-private key file pair for Linux VMs. With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication.
