Add a new SSH key

A new laptop needs SSH access. Its public key is sitting in ~/newkey.pub. Append it to ~/.ssh/authorized_keys so logins from that machine are accepted — without clobbering any keys already there.

Your mission

  • Append the contents of `~/newkey.pub` to `~/.ssh/authorized_keys`

Everything here is simulated and safe — break things freely. Your progress is tracked on the right and saved in this browser.
