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.
