Once you have entered the Gen Key command, you will get a few more questions:
Create a new repository, or reuse an existing one. Generate a new SSH key: ssh-keygen -t rsa -C '[email protected]' Copy the contents of the file /.ssh/idrsa.pub to your SSH keys in your GitHub account settings. SSH (Windows) Windows 10 version 1803 comes with the Secure Shell (SSH) client as an optional feature installed at C:Windowssystem32openssh.If you have ssh.exe and ssh-keygen.exe there, skip forward to Generate SSH key (Windows). Download the latest OpenSSH-Win64.zip file from Win32-OpenSSH releases; Extract it to the same c:tools folder or another folder in your path.
You can press enter here, saving the file to the user home (in this case, my example user is called demo).
It's up to you whether you want to use a passphrase.
Entering a passphrase does have its benefits: the security of a key, no matter how encrypted, still depends on the fact that it is not visible to anyone else. Should a passphrase-protected private key fall into an unauthorized users possession, they will be unable to log in to its associated accounts until they figure out the passphrase, buying the hacked user some extra time. The only downside, of course, to having a passphrase, is then having to type it in each time you use the Key Pair.
The entire key generation process looks like this:
The private key (identification) is now located in /home/demo/.ssh/id_rsa
Copy the Public Key

You can copy the public key into the new machine's authorized_keys file with the ssh-copy-id command. Make sureto replace the example username and IP address below.
Alternatively, you can paste in the keys using SSH:
No matter which command you chose, you should see something like:
Now try logging into the machine, with:

Now you can go ahead and log into [email protected] and you will not be prompted for a password. However, if you set a passphrase, you will be asked to enter the passphrase at that time (and whenever else you log in in the future).

Disable the Password for Root Login
Once you have copied your SSH keys unto your server and ensured that you can log in with the SSH keys alone, you can go ahead and restrict the root login to only be permitted via SSH keys.
In order to do this, open up the SSH config file:
Within that file, find the line that includes PermitRootLogin and modify it to ensure that users can only connect with their SSH key:
