SiteGround uses key pairs for SSH authentication purposes, as opposed to plain username and password. More information on SSH keys is available here. You can generate an SSH key pair in Mac OS following these steps: Open up the Terminal by going to Applications - Utilities - Terminal.
Use this command to generate RSA key pairs for your Cisco device (such as a router). keys are generated in pairs–one public RSA key and one private RSA key.
If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys.
NOTE: Before issuing this command, ensure that your router has a hostname and IP domain name configured (with the hostname and ipdomain-name commands).
You will be unable to complete the cryptokeygeneratersacommand without a hostname and IP domain name. (This situation is not true when you generate only a named key pair.)

This command is not saved in the router configuration; however, the RSA keys generated by this command are saved in the private configuration in NVRAM (which is never displayed to the user or backed up to another device) the next time the configuration is written to NVRAM.
Modulus Length
When you generate RSA keys, you will be prompted to enter a modulus length. The longer the modulus, the stronger the security. However, a longer modules take longer to generate (see the table below for sample times) and takes longer to use.
The size of Key Modulus range from 360 to 2048. Choosing modulus greater than 512 will take longer time.
Cisco IOS software does not support a modulus greater than 4096 bits. A length of less than 512 bits is normally not recommended. In certain situations, the shorter modulus may not function properly with IKE, so we recommend using a minimum modulus of 2048 bits.

How to Generate SSH Keys on Windows using PuTTY Download
In order to Generate an SSH Key on Windows, you will need todownload PuTTY. PuTTY is a free SSH and telnet client for Windows.
PuTTYgen is a robust SSH key pair generation tool that comes via PuTTY Download that will help you to generate an SSH-2 RSA key pair. This is the type of SSH key needed to access a SkySilk VPS with SSH.

Be sure to Save your private key!

If you're using putty, you'll need to specify the private key when you're logging in, as follows:
1. In the putty connection configuration screen, expand Connection -> SSH -> Auth
2. Click the Browse button, and select your previously-created private key
3. Return to the Session Category. Name and save the session for easy future access.

4. Login to your SkySilk VM now that your SSH key has been configured.
How to Generate SSH Keys on Mac OS X & Linux
1. Search for and Launch the Terminal app.
2. Enter the following code and press enter:
3. Press ENTER to store the key in the default folder /Users/Username/.ssh/id_rsa).
4. Type a passphrase (characters will not appear in Terminal).
5. Confirm your passphrase to finish SSH Keygen. You should get an output that looks something like this:
6. Copy your public SSH Key to your clipboard using the following code:
Generator connection cabinet. 7. Use ctrl+v or right-click and paste to paste your public SSH Key where it needs to go!
8. Login to your SkySilk VM now that your SSH key has been configured.
NEVER SHARE YOUR PRIVATE SSH KEY WITH ANYONE!
What is SSH and Why do I need it?
The need to facilitate secure communication between system operators and their respective system led to the development of SSH or Secure Shell. SSH works on the premise of challenge-response ('lock' and 'key') using public and private hash values. A user installs the private key into a private location in their user directory and presents the public key any time a console session is established. The necessary tools to generate SSH keys are already preset and virtually every modern Unix-like operating system, including Linux and MacOS X. On Windows, puttygen does the job.
The public key will always follow the following syntax:

where the hash value would be the length of the cipher strength chosen at generation, usually 2048bit. That WHOLE string is what you copy into your ssh key field during VM generation.The PRIVATE key you have generated should be saved securely on your computer because it is the only credential necessary to log in to the machine; if it is compromised it can be used to gain root access to your machine which isn't good!
