Create a new SSH key
An SSH key will help you to create a secure connection between computers. Creating an SSH key creates both a Public and a Private key. Here is how to create a new key:
Press the + button in the top-left corner of the window.
Select Secure Shell Key from the list.
Enter a description for the key. The key description will help you to identify the key later. For example, you could enter the date for the day, something about how the key will be used, or the server name on which you intend to install the key. The description field is optional, and how you describe the key is entirely up to you.
You can also change default settings for encryption type or key strength.
At this point, you can just create your key, or create your key and install it on a remote computer to enable password-free login.
