X - Creating and using SSH keys

Don't use a password. Generate a passphraseless SSH key and push it to your VM.

Instructions

If you already have an SSH key, you can skip this step… Just hit Enter for the key and both passphrases:

localhost:~$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa): .ssh/mykey
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/username/.ssh/mykey.
Your public key has been saved in /home/username/.ssh/mykey.pub.

Copy your keys to the target server:

localhost:~$ ssh-copy-id -i .ssh/mykey user@hostname
user@hostname's password: ••••••••

Now try logging into the machine, with ssh 'user@hostname' to verify the keys we’ve added:
```
localhost:~$ ls ~/.ssh/authorized_keys
```
Finally check you can log in using your new key…
```
localhost:~$ ssh id@server
user@hostname:~$ 
```
You may also want to look into using ssh-agent if you want to try keeping your keys protected with a passphrase.
