→Switching to SSH keypair authentication:
# With a second terminal, verify that you can login to your VM's SSH from your personal computer without a password (keypair authentication). Do not move on to the next step until you’re sure.
#* Login the same way as before. '''If you aren't asked for a password, then keypair authentication has succeeded.'''
# Save both keys (''id_rsa'' and ''id_rsa.pub'') to secondary, portable location. This can be online storage like OneDrive or Dropbox, or to a USB drive. You will need your keys when you come to class to log in to your Linux VM going forward.
