Commands:

$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/username/.ssh/id_rsa): 
/Users/username/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/username/.ssh/id_rsa.
Your public key has been saved in /Users/username/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:xCFSgzCQb5J5yjX911Xvdav018XVmXbfibdoEYxjXs0
