SSH with no authentication

[pierrestoffe]

My remote server is part of a Tailscale network. The firewall on that server has all ports closed, but since Tailscale SSH is enabled I can still connect to it over SSH. As per Tailscale's documentation, they use the authentication type "none" (no ssh key, no password).

With Tailscale SSH, Tailscale will authenticate and encrypt the connection over WireGuard, using Tailscale node keys. The SSH client and server will still create an SSH connection, but during the SSH protocol's authentication phase, the Tailscale SSH server already knows who the remote party is and takes over, not requiring the SSH client to provide further proof (using the SSH authentication type none).

I do so on a daily basis using my terminal but also with dev apps such as VSCode, TablePlus and Transmit without any issue. It doesn't work with Ray though since it forces using either an SSH key or a password.

Could Ray make authentication optional, or add a third "None" option?

Edit: a temporary solution is to set a random password, since Tailscale takes over the connection and ignores the password.
