![]() ![]() ![]() Supported SSH key formatsĪzure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Your public key can be shared with anyone, but only you (or your local security infrastructure) should have access to your private key. You do not need a separate pair of keys for each VM or service you wish to access. If the client has the private key, it's granted access to the VM.ĭepending on your organization's security policies, you can reuse a single public-private key pair to access multiple Azure VMs and services. When you use an SSH client to connect to your VM (which has the public key), the remote VM tests the client to make sure it has the correct private key. The private key remains on your local system. We recommend connecting to a VM over SSH using a public-private key pair, also known as SSH keys. Although SSH provides an encrypted connection, using passwords with SSH connections still leaves the VM vulnerable to brute-force attacks. SSH is an encrypted connection protocol that provides secure sign-ins over unsecured connections. Azure doesn't support provisioning public keys to Windows machines automatically, however you can copy the key using the RunCommand extension. You can authenticate to Windows machines using either username and password or SSH keys. To start the VM, select Start at the top of the page. ![]() On the Overview tab, in the essentials section, verify the status of ![]() To learn more about adding a public IPĪssociate a public IP address to a virtual machine Next to Public IP address, then your VM has a public IP.
