help keys

Your keys are in ~/.ssh/authorized_keys, one per line. To add one, for
a second computer say, paste its public key on a new line:

  nano ~/.ssh/authorized_keys

Keep the permissions tight or SSH will ignore the file:

  chmod 700 ~/.ssh
  chmod 600 ~/.ssh/authorized_keys

Lost every key you had? Write to admin@runv.club from the email you
signed up with.
