“With Tailscale SSH Console, your browser becomes a Tailscale client, and joins your tailnet in the same way as any other device that you run Tailscale on.”
Tailscale compiled its Go client to WebAssembly, so a browser tab joins your private network as a real node with its own WireGuard keys. No passwords, no authorized_keys file. It started as an engineer’s vacation hack. It’s also one more reason your whole network now depends on Tailscale’s coordination server.
