There tin hold out many reasons why you lot don't desire root to login directly. You may hold out concerned almost security. Brute forcefulness attacks past times guessing the password are common. In improver to security, you lot may hold out concerned almost traceability. If at that topographic point are to a greater extent than than 1 administrator on a system, together with they tin all login equally root, together with then it is impossible to delineate who had done what (after all, it is the same root account).

As an alternative, nosotros tin configure sshd such that root tin remote login directly, merely exclusively amongst world primal authentication. From the safety perspective, world primal authentication offers much meliorate protection than password. If beingness able to delineate the user is non that of import (say at that topographic point is exclusively 1 root user), together with then you lot may wishing to reckon such a configuration. Note: remote login past times root using password authentication is however disallowed.

1. As root, edit the sshd daemon configuration file (/etc/ssh/sshd_config).
2. Modify the PermitRootLogin together with the PubkeyAuthentication parameters to convey the next values.
