You can even develop keys Along with the Azure CLI While using the az sshkey build command, as explained in Produce and store SSH keys.
Based upon your Group's safety policies, you could reuse one general public-personal key pair to entry several Azure VMs and solutions. You don't need a different pair of keys for every VM or support you wish to entry.
Our suggestion is to gather randomness throughout the total installation on the running method, help you save that randomness within a random seed file.
