Small SSH hardening on my NixOS server 🔐

Small SSH hardening on my NixOS server

Before:

services.openssh.enable = true;

Now SSH login is key-only —
passwords disabled:

services.openssh = {
enable = true;
settings = {
PasswordAuthentication = false;
KbdInteractiveAuthentication = false;
};
};

More security with minimal effort
