SSH allows for both password based authentication, as well as public key authentication. Public key authentication is generally regarded as being more secure, as it isn’t as prone to brute force login attempts (if you disable password based authentication). The private key can also have a passphrase associated with it, which makes public key authentication even more secure if needed.
Sometimes cloud servers will let you put a public key in as a authorized authentication key when the cloud server is created, preventing the need for password based authentication to be enabled by default.

If you use the Azure CLI to create your VM with the az vm create command, you can optionally generate SSH public and private key files using the -generate-ssh-keys option. The key files are stored in the /.ssh directory unless specified otherwise with the -ssh-dest-key-path option. Red Hat Enterprise Linux 6 uses SSH Protocol 2 and RSA keys by default (see Section 14.1.3, “Protocol Versions” for more information). Important Do not generate key pairs as root, as only root would be able to use those keys.

- In the Number of bits in a generated key box, enter 2048. Click Generate to generate a public/private key pair. As the key is being generated, move the mouse around the blank area as directed. (Optional) Enter a passphrase for the private key in the Key passphrase box and reenter it in the Confirm passphrase box.
“Identifying comment” can be any string that will assist in determining which key this is. “username@hostname” of the machine where you are connecting from would be a good example.

eg:
This will generate two files, “keypair” and “keypair.pub”. “keypair” being the private key that you need to keep secure, and “keypair.pub” being the public key, that can be put on servers that you want to be able to log into with the private key.
Change the filename to suit your needs. This example uses “keypair” for the examples.
The contents of the public key file “keypair.pub” can be inserted into the ~/.ssh/authorized_keys file on the machine that you want to be able to connect into remotely. This must be done for the specific user.

If you have chosen to copy the public key file to the remote host instead, you can issue the following command instead:
Logging into remote ssh server using the private key file
To connect to the remote host using SSH you can use the following command:

This will use the private key called “keypair” created earlier, and assuming the remote server has the public key added to the “user” users authorized_keys file, you should be able to log into the remote system.
