Cowboy for Herdr

Adding a host no longer means pasting a private key into your phone. Pick Password, type the login you already use for that machine, and tap "Sign in and install a key". Cowboy signs in once, leaves a key of its own on the machine the way ssh-copy-id does, and forgets the password — it is never stored, on the phone or anywhere else. Undo it whenever you like by deleting that one line from ~/.ssh/authorized_keys. The first time you connect to a machine, Cowboy now shows you its SSH fingerprint and waits. Nothing is sent until you say it matches, so a password only ever reaches the machine you meant. Hosts behind a second factor work too: you answer it once, when you set the host up, rather than every time Cowboy reconnects. Pasting a private key still works for anyone who prefers it, and Tailscale SSH still needs nothing at all. Also fixed: on the host screen, "Forget host key" and "Delete host" ran off the edge of narrow phones.
