# Secure Shell Access

Secure shell (SSH) access to your machine can be enabled by setting:

     = true;

By default, root logins using a password are disallowed. They can be disabled entirely by setting to `"no"`.

You can declaratively specify authorised RSA/DSA public keys for a user as follows:

    users.users.alice.openssh.authorizedKeys.keys =
      [ "ssh-dss AAAAB3NzaC1kc3MAAACBAPIkGWVEt4..." ];
